For a solid sphere of radius "R" and total charge "Q" let the charge distribution be `rho=(Qr)/(pi R^(4))`.Then,for a point P distinct `r_(1)` from centre of sphere (`r_(1)`

Let rho(r)=(Qr)/(piR^(4)) be the charge density distribution for a soild sphere of radius R and total charge Q. For a point P inside the sphere at a distance r_(1) from the centre of the sphere, the magnitude of electric field is

Figure shows a uniformly charged sphere of radius R and total charge Q. A point charge q is situated outside the sphere at a distance r from centre of sphere. Find out the following : (i) Force acting on the point charge q due to the sphere. (ii) Force acting on the sphere due to the point charge.
