Concept:
The potential on surface of a sphere with charge q and radius r is
Given:
Q=4×10^-8C
∵ Diameter = 8cm
∴ R=4cm =0.04 m
Find:
Electric potential(V) on the surface of sphere
Solution:
We know that the value of Coulomb’s constant is:
The electric potential on the surface on the hollow cylinder with radius 4 cm is -9000V
