Three concentric spherical shells have radii a, b and

\mathrm{c}(\mathrm{a} < \mathrm{b} < \mathrm{c})

and have surface charge densities

\sigma,-\sigma

and

\sigma

respectively. If

V_A, V_B

and

\mathrm{V}_{\mathrm{C}}

denote the potentials of the three shells, then, for

V_A=V_C

, we get -

View answer and explanation

Correct option: D

c=a+b

Option D (

c=a+b

) is correct because it satisfies the condition

V_A = V_C

when the potentials are calculated for the three concentric shells.
