the ans is (C)
n
the xplaination is
as the sphere is floating its total weight is the net bouyancy force.let the volume of it be V
now
weight of the sphere is VPg
where P is the density of the material of the sphere
net bouyance is V/2*08*g+V/2*13.6*g
on equating these two we get the ans

The  Indian Institute of  Technology  is now a household name  in India  and the highest  aspirational goal  for many brilliant  students.Jawarharlal Nehru  is usually  credited  with the establishment  of  IITs.
 
Actually the story goes back a few years before  Nehru  became Prime Minister.Sir Ardeshir Dalal,a member of the Viceroy's executive council,proposed three steps to promote  technology  in the country:
 
1)The establishment  of science & technology laboratories under the council of Scientific and Industrial Research(CSIR).
2)World class technology institutes  to provide manpower for research.
3)As a short term measures,special scholarships in American universities for able young graduates.
He did mot live to see his dream fulfilled but had to lay the foundation of a future IIT  by appointing  a committee under  Sir N.R.Sankar.

History:
              At  this stage,politics took a hand.Dr.B.C.Roy,CM  of West Bengal ,impetuosly demanded that the first IIT be located in his state and be started immediately.He had a strong case because at that time WB  was the most industrialised state in the country .Dr.B.C.Roy had the support of Sir J.C.Ghosh,a former Director  of Indian Institute of Science,who in fact became the first director  of IIT Kharagpur .
              Kharagpur was choosen as the location for the first IIT  only because it had the Hijlee jail,which was being closed down and therefore provided a large ,readymade building .Gauhati too started as a political whim.When PM Rajiv Gandhi went to Assam to propitiate agitating students,he was presented a list of demands -of which one was an IIT for Assam.He agreed to it on the spot .Similarly ,the UNIV  of Roorkee was converted into an IIT because Murli Manohar Joshi wanted one for his state as the Delhi College of Engineering.The British were pursuaded  to support it because the Russians,the Americans and even Germans had committed to support an IIT each.At the instance of the British,the Delhi College was converted into an IIT.

Incomplete Fragment:

The  Sakar Committee Report is an incomplete fragment;most of it is a detailed proposal of how to set up a hydraulic engineering laboratory .However,it have gems of wisdom in its introductory pages.One of its important recomendations of the chief executive from the chairmanship of the executive body.
In universities,Vice Chancellors combine both  positions.Thus,while a VC is like a fighter  with a sword in each hand,IIT Directors hold a sword in one hand and a shield in the other.

The IITs were lucky to come up at a time of excruciating foreign  exchange crunch.Short of funds,Nehru persuaded Russian Gov. to fund the one in Bombay.The Germans,who  were accumilating embarassingly,large trade surpluses  with India,offered to setup the third one in Madras.
Not to be left behind,the Americans brought in a strong team to start the IIT in Kanpur.

International support conferred two special privileges on the IITs.One,it provide foreign experts,who added much glamour and some academic brilliance.Two,the IITs became the only institutions in the country with substantial foreign exchange to establish modern laboratories.Both ways,IITs got an advantage over traditional universities.

The IITs were also lucky in having persons of grit as Directors.They were ably supported by a far-seeing bureacrat in Delhi.L.S.Chandrakant was nit from the IAS and had an academic background.He consciously subjugated his authority as Educational Adviser for Technical Education to promote academic autonomy in the IITs.It was due to such a fortuitous combination of circumstances tha strong foundations were laid for the IITs.
               For decades,very few politicians were conscious of what IITs were.They offered no opportunities for political or financial patronage.Often they were confused with ITIs-beneath  the attention of MPs.On the other hand,for  the Education Ministers of those days,the IITs were the jewel in their crown-to be cherished,nurtured and protected.The times have changed.The IITs have now become political pawns to buy political favours.At present,neither Ministers nor bureaucrats see any value in promoting quality;for them the IITs are a commodity,to be bought and sold in the political market place.

Brain drain:
                Two years ago the U.S. congress passed a special resolution  commending the contributions made by IIT graduates to the American economy.Such praise is both an advantage and a handicap.It recognise the quality of education IITs provide so its is an advantage.where as it is a handicap because it follows that IITs have not done enough for their own country.

Many IIT graduates did forsake their  country;fewer of them do so these days.Few people apprciate the reason:the talents of IIT graduates are not valued here.Indian Industry depends mainly on foreign know-how ; it needs only technicians,not IIT graduates.In the government,engineers have wait almost till retirement to reach responsible positions;even then ,they have to report to an IAS officer nearly 20 years younger.Both ways,IIT graduates have little scope and less autonomy to practise their skills.
                The fact that IIT graduates are badly under-rated is usually forgotten.The fact that they can face the toughest  international competition  is deemed to be a flaw than as an asset.The Indian Gov. and Indian Industry too.has much to for squandering some of the finest talent  available anywhere in the world.

Academic independence:
                 What about the next 60 years?Unlike L.S.Chandrakant,present day bureaucrats  have no respect for academic  autonomy.IIT directors  do not have  the grit  that their predecessors like Dr M.S.Muthanna  had  and fought   a determined fight against political interference.IIT perquisites used  to  be extraordinary;salaries  quite satisfactory.That is no longer true . IITs cannot  attract faculty  the way they used to ;even  if  they can, the government with its insistence  on caste based reservation in faculty recruitment will  not allow them to do  so.
                ""  IITs used   to get outstanding  students  through a  national  entrance examination.That test has now become anachronistic;tutorial  institutes have proliferated and feed rote learners  rather than  intellectuals.""
                 To  overcome these threats ,IITs should a)learn to face political/administrative interference;b)attract top quality academics  and c)devise a better system for admitting students.

In   a  novel   the  main  charecter  "Jean"   an  escaped  prisoner  was  noted  for  his  ability  to    climb   up  the  corner   formed  by  the   intersection   of 
two   vertically  perpendicular   walls.Find  the  minimum   force  with  which  he  had  to  push   on  the  walls   while  climbing.What  is  the  minimum  coeffocient   of   static  friction   required   for  him  to  be   able  to   perform  such  a  feat.

/1.we have

series  limit  for  lyman
             :                                       V= C*R
 
 
SERIES  LIMTI  FOR  BALMER
:                                               V2=C*R/4
 
NOW  THE   DIFF  IS     V=c*3/4R

1.Charecteristic x-rays are the group of x-rays produced due to electronic transitions in the target metal
as per this "char x-rays " are nothing but the radiation due to transition of electrons in the target metal
hence their wavelength is independent of accelerating potential.
2.Well for this i can't xplain bcoz u have mentioned that electrons get trapped in the target i hope this doesn't happen.
But when u think of charecteristic x-rays the fast moving electrons hit and transfer thier energy to the electrons inside the target .By acquiring sufficient energy the get out of the atom and the atomic transitions which continue further lead to characteristic x-rays .
3.This  may  happen  bcoz  their  wavelengths may  equal if  the  transition energy  and  the  energy  of  continuous x-ray  photon may  be  equal  sometimes.
