Consider a uniform charge distribution with charge density 2 C/m^3 throughout in space. If a Gaussian sphere has a varible radius which changes at the rate of 2 m/s find the value of K. The region between two concentric spheres of radii a and b respectively has volume charge density rho = A/ r then value of rate of change of flux is proportional to rk ( r = radius of sphere ). Then
