An irregular shaped non conductor has some charge distribution. The potential difference between the two points A and B in it is V. If it is now enveloped in an spherical non conducting shell having uniform charge distribution in it, the new potential difference between the points (neglect any induction due to presence of charge)

Options

A. is greater than V
B. is less than V
C. is equal to V
D. depends on the relative position of inner nonconductor vis-a vis outer non conducting

Answer

C

Explanation

The field due to the uniformly charged shell at an inside point is zero.
Hence potential difference will not change
