The electric field due to uniform distribution of charge on a spherical shell is zero.
- A
Every where
- B
Only at the center of shell
- C
Only inside the shell
- D
Only one side of the shell
Gauss's Law shows that the electric field everywhere inside a spherical shell of uniform charge density is 0.
Electric field strength is maximum at the surface of the sphere so everywhere is incorrect.
B is not the answer because electric field strength is not only zero at the center but the whole of the inside of the sphere.
Electric field strength and force are zero inside the sphere because the charges are stationary, so C is correct.
At the shell of the sphere, the electric field strength is maximum, not zero.
