Consider the classical model of an electron such that a nucleus of charge +e is uniformly distributed within a sphere of radius`2Å`. An electron of charge -e at a radial distance `1Å` moves inside this sphere. Find the force a!tracting the electron on to the centre of the sphere. Calculate the frequency with which the electron would oscillate about the centre of the sphere, if released from rest at this radial distance.
