i am a class 12 student from ISC background.can anyone suugest a suitable physics project on optics other than optical fibre,prisms,lenses or other common topics.

i would surely rate the answers and suggestions if satisfied...

Try out Solomon.i think it is too good for +2 level with detailed mechanism and next try out all other questions related to it and i am sure u would be able to solve all questions.
For mcq practise try out TMH chemistry for IITJEE.it has some quality questions with detailed soultions.

hey man!!!!what i learnt from my friend that the solution book of hc verma is also available from most probably arihant or other publishers.i got one from him of H.C.Verma part-2.

anyone,kindly reply if u know.

hey pratt!!!!i would like to share with you my plaaning.
in 1 week try to utilise 5 days for studying ahead with class-12 and then the next 2 days revising older portions froms untouched books of respective subjects.this way u r new portions can be tackled with retention of old portions.

is the answer :-lnx/(1+lnx)^2

it is around Rs.515/- and also comes with a C.D with tasks and organic models.

bhai!!!i dont have sanyal and sanyal.i usuaaly do from solomons and arihant.

hey friends!!does anyone knows the site for solomons guide book or is it available in yhe market readily as the book itself...

send me please too.

thanx in advance.

solution:::
Let T be the tension.
@ be the angle the string makes with the vertical in the equilibrium condition
m=mass of the two balls.
q=charge on each
the Tcos@=mg.........(i)
and
Tsin@=9X10^9XqXq/(0.03X0.030).........(ii)
but u have sin@as 1/20
putting in (ii), u can get the value of T.
using the value of T and cos@,u can get the value of m.
kindly rate the answer if correct.

kindly reply whether or not the ans is correct so that i can give u the steps to arrive at this answer.
