A charge is uniformly distributed inside a spherical body of radius `r_(1) = 2 r_(0)` having a concetric cavity of radius `r_(2) = r_(0)` (`rho` is charge density inside the sphere). The potential of a point P at a distance `(3 r_0)/(2)` from the centre is

B. `(101 rho r_0^2)/(72 epsilon_0)`
C. `(17 rho r_0^2)/(72 epsilon_0)`
D. none of these

Answer

B
