defence exam Army Havildar SAC Mock Test Series 2025 Physics Electric Potential Potential of Charged Isolated Conductor
Three concentric spherical shells have radii a, b, and c (a < b< c) and have surface charge densities σ, -σ, and σ respectively. If VA, VB and VC denote the potentials of the three shells, then for c = a + b, we have:
1
VC = VB ≠ VA
2
VC ≠ VB ≠ VA
3
VC = VB = VA
4
VC = VA ≠ VB
