A spherical portion has been removed from a solid sphere having a charge distributed uniformly in its volume as shown in the figure. The electric field inisde the emptied space is

A very small sphere having a charge q, uniformly distributed throughout its volume, is placed at the vertex of a cube of side a. The electric flux through the cube is

Find the electric work done in bringing a charge q from A to B in a sphere of charge Q distributed uniformly throughout its volume. .

A spherical conductor of radius 12 cm has a charge of 1.6xx10^(-7)C distributed uniformly on its surface. What is the electric field (a) inside the sphere (b) just outside the sphere (c ) at a point 18 cm from the center of the sphere ?

A spherical shell having charge +Q (uniformly distributed) and placed as shown. Find the force between shell and the point charge (r gt gt R) .

A solid hemispherical uniformly charged body having charge Q is kept symmetrically along the y -axis as shown in the figure. The net electric field at ( d , 0 , 0 ) is

The uniform solid sphere shown in the figure has a spherical hole in it. Find the position of its centre of mass.

Assertion: Electric potential on the surface of a charged sphere of radius R is V. Then electric field at distance r=R/2 from centre is V/(2R) . Charge is distributed uniformly over the volume. Reason: From centre to surface, electric field varies linearly with r. Here r is distance from centre.
