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 . 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 potentialenergy changes by .
Statement 2 : The electric field at a distance r (r < R) from the centre of the sphere is
