In a spherical charge distribution, volume charge density varies as rho=Cr^(-1) for r_(1) lt rlt r_(2) as shown. Here C is a positive constant. When a point charge q is kept at the centre of the sphere, the electric field strength in the region r_(1) lt r lt r_(2) will be a constant. For this find the value of C.

1.	In a spherical charge distribution, volume charge density varies as rho=Cr^(-1) for r_(1) lt rlt r_(2) as shown. Here C is a positive constant. When a point charge q is kept at the centre of the sphere, the electric field strength in the region r_(1) lt r lt r_(2) will be a constant. For this find the value of C.
Answer» SOLUTION : `C=q/(2pir_1^2)`
