Two non-conducting spheres of radii $R_{1}$ and $R_{2}$ and carrying uniform volume charge densities $+ ρ$ and $- ρ$ , respectively, are placed such that they partially overlap, as shown in the figure. At all points in the overlapping region :-

Options:(select one or more)

Answer:

C, D

Solution:

$E = \frac{ρ A P}{3 ϵ _{0}} - \frac{ρ BP}{3 ϵ _{0}}$

$E = \frac{ρ A B}{3 ϵ _{0}}$

This is constant in magnitude and direction throughout the overlap.

Potential is not constant because the field is nonzero.

Hence C and D.
