Questions
A spherical conductor of radius 2m is charged to a potential of 120 V. It is now placed inside another hollow spherical conductor of radius 6m. Calculate the potential to which the bigger sphere would be raised
detailed solution
Correct option is D
If charge acquired by the smaller sphere is Q then it’s potential120=kQ2 ….(i)Also potential of the outer sphere V=kQ6 …(ii)From equation (i) and (ii) V = 40 voltTalk to our academic expert!
