There are three conecentric hollow spheres of radii a, b and c and they are charged with charges `q_(1),q_(2)` and `q_(3)` respectively. Calculate the potential of the spheres.

Two hollow concentric non-conducting spheres of radius the a and b (a gt b) contain charges Q_(a) and Q_(b) respectively. Prove that potential difference between the two spheres is independent of charge on outer sphere. If outer sphere is given an extra charge, is there any change in potential difference ?

The concentric, thin metallic spheres of radii r_(1) and r_(2) (r_(1) gt r_(2)) carry charges q_(1) and q_(2) respectively. Then the electric potential at distance r (r_(2) lt r lt r_(1)) will be (1)/(4pi epsilon_(0)) times
