This question has statement-1 and statement-2. Of the four choices given after the statements, choose the one that best describes the two statements. 

An insulating solid sphere of radius R has a uniformly positive charge density $\mathrm{\rho }$. 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 : When a charge ‘q’ is taken from the centre to the surface of the sphere, its potential energy changes by  $\frac{q\rho }{3_0}$ 
Statement-2 : The electric field at a distance r (r<R) from the centre of the sphere is $\frac{\rho r}{3{\mathrm{\epsilon }}_0}$
