Two uniformly charged concentric hollow spheres of radii R and 2 R are charged. The inner sphere has a charge of 1 µC and the outer sphere has a charge of 2 µC of the same sign. The potential is 9000 V at a point P at a distance 3R from the common center O. What is the value of R?

CHECK THE SOLUTION.
(1m)
Sol.
V p = 9000 V
∴ 
= 9000 V
or 
. [1µc + 2 µc] = 9000
∴ 
= 9000
or R = 1 m
