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)`

Metallic sphere of radius R is charged to potential V. Then charge q is proportional to

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.

Let P(r)=(Q)/(piR^4)r be the charge density distribution for a solid sphere of radius R and total charge Q. For a point 'p' inside the sphere at distance r_1 from the centre of the sphere, the magnitude of electric field is:

A charge +Q , is uniformaly distributed within a sphere of radius R. Find the electric field, due to this charge distribution, at a point distant r form the centre of the spehre where : (i) 0 lt r lt R and (ii) r gt R
