Consider two spheres with charge density $+ρ$ and $-ρ$ respectively. The radius of both the spheres is $R$. The centers of the two spheres are at distance $d$ from each other (Here $d<2R$). There is no charge in the intersecting region.
Consider a point $P$ on the line connecting the centers of the two spheres. $P$ is at a distance $x$ from the center of the positively charged sphere (Here $x>R$).
Determine the electric field (magnitude and direction) at $P$.
