Question

$A$ and $B$ are concentric conducting spheres. $A$ is positively charged while $B$ is earthed as shown in the figure, then:

• A. A and B bothhave same chargedensities.
• B. The electric field between A and B is zero.
• C. The potential inside A is zero.
• D. Inside the sphere A the electric potential is constant.

Answer 1

Answer: (D)

Potential inside conductor is constant.
