Questions
A solid conducting sphere has a charge - 2Q and is surrounded by a neutral concentric hollow conducting spherical shell of double the radius. The potential difference between the solid sphere and the shell is V. The shell is, now given a charge - 3 Q; the new potential difference between them will be :
detailed solution
Correct option is A
Any charge given on the outer sphere will not change the potential difference.Talk to our academic expert!
