Question : 75

Total: 100

An insulating solid sphere of radius R has a uniformly positive charge density ρ . 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 outside the sphere. The electric potential at infinite is zero.
Statement -1 When a charge q is taken from the centre to the surface of the sphere its potential energy changes by

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