1. if two plates of parallel plate capacitor are given diff. charges Q1 & Q2then what would be V.(capacitance is C).

2.If a capacitor is fully charged & den connected to another similar capacitor den will discharging takes place???

see for first one learn how a parallel plate capacitor is formed then try doing it...if still u r having any problem then nudge me.....

for the second one discharging will take place

what was ur cousin's rank ?

are you sure that eq. resistance b/w B and C is r/2 ?

sorry yaar i meant.....is the equivalent resistance b/w A and B equal to R?

where R is resistance in each part

is the equivalent resistance b/w A and B equal to R where R is resistance b/w B and C

i will explain....first tell me the answer.....and i am not guessing

I believe he won't get a shock because the aluminium sheet is electrically neutral.

i think answer should be (a)

yaar.....i think focus on theory part...coz if you know theory only then you can solve JEE level questions.....and after reading just take a look at some imp. examples...
......plan ur day by giving high priority to ur state board.....then i thing if you take out atleast 3-4hrs for revising JEE stuff it will be fine
don't try covering everything for FIITJEE tests....just TRY covering max.

yup i passed but i am reappering as a private candidate in physics and maths

i passed 12th in 2007....but i applied for improvement...and will be writting improvement exam for physics and maths in CBSE 2008....which means i am apperaing as a private candidate....

What am i supposed to write in -

1) percentage in 12th class

2) year of passing/apperaing of 12 class

3) Name and Address of the school/college from where passed/appering of12th class

i am getting 5 as answer....i.e. (a)

great job........

great thinking
