An insulating solid sphere of radius R has a uniformaly positive charge density `rho`. As a result of this uniform charge distribution there is a finite value of electric potential at the centre of the sphere, at the surface of the sphere and also at a point out side the sphere. The electric potential at infinity is zero.
Statement-1: Wgen a charge 'q' is taken from the centre to the surface of the sphere, its potential energy charges by `(qrho)/(3 in_(0))`
Statement-2 : The electric field at a distance `r (r lt R)` from the centre of the the sphere is `(rho r)/(3in_(0))`

Options

A. Statement-1 is true, Statement-2 is true and Statement-2 is the correct explanation of Statement-1
B. Statement-1 is true, Statement-2 is true and Statement-2 is not the correct explanation of Statement-1
C. Statement-1 is true, Statement-2 is false
D. Statement-1 is false, Statement-2 is true

Answer

D
