Question:

A spherical shell of radius R is carries a uniform surface charge q. Take the reference point at ∞

If a second uniformly charge shell (Q) of radius R' is placed concentrically such that R'>R, how will the value of potential change at r<R?

Options:

increases

decreases

remains constant

none of these

Correct Answer:

increases

Explanation:

because the potential inside will be from both shells of radii R and R'
