The region between two concentric sphere...

The region between two concentric spheres of radii 'a' and 'b', respectively (see figure), have volume charge density `rho=A/r`, where A is a constant and r is the distance from the centre. At the centre of the spheres is a point charge Q. The value of A such that the electric field in the region between the spheres will be constant, is:

A

`(Q)/(2pi(b^(2)-a^(2)))`

B

`(2Q)/(pi(a^(2)-b^(2)))`

C

`(2Q)/(pia^(2))`

D

`(Q)/(2pi a^(2))`
