AIPMT MAINS 2009 Physics Potential due to Spherical Shells MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Three concentric spherical shells have radii a, b and c (a < b < c) and have surface charge densities σ, -σ and σ respectively. If V A, V B and V C denote the potentials of the three shells, then for c = a + b, we have:
A
V C = V B ≠ V A
B
V C ≠ V B ≠ V A
C
V C = V B = V A
D
V C = V A ≠ V B
Correct Answer
Option D
Detailed Explanation
The potential at a point due to a charged shell depends on the charge distribution and geometry. For concentric shells, the potential at the outer shell is influenced by the inner shells, leading to equal potentials for shells with the same charge density.
