Two non- conducting spheres of radii R₁ and R₂ are carrying uniform volume charge densities +$\rho$ and -$\rho$  respectively, are placed, such that they partially overlap, as shown in the figure. At all points in the overlapping region

Answer:

Explanation:

For electrostatic field,

 E_p= E₁+E₂

  =   $\frac{\rho}{3\epsilon_{0}}C_{1}P+\frac{(-\rho)}{3\epsilon_{0}}C_{1}P$

  =  $\frac{\rho}{3\epsilon_{0}}(C_{1}P+PC_{2})$

  $E_{p}=\frac{\rho}{3\epsilon_{0}}C_{1}C_{2}$

 For  electrostatic potential: since the electric field is non zero so it is not equipotential
