    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 uniform positive charge density p. 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 (qp)/(3epsilon _0) Statement - 2 : The electric field at a distance (rltR) from the centre of the sphere is (pr)/(3epsilon _0)
