Question

The electrostatic potential on the surface of uniformly charged spherical shell of radius R = 10 cm is 120 V. The potential at the centre of shell, at a distance r = 5 cm from centre, and at a distance r = 15 cm from the centre of the shell respectively, are :

TestHub · Accepted Answer

Potential inside shell is equal to potential on surface V in ​ = V surface ​ = R kQ ​ = 120 V at r = 15 cm V = r kQ ​ = 15 120 × 10 ​ = 80 V
