Positive charge Q is uniformly distributed throuhout the volume of a dielectic sphere of radius R. A ponit mass having charge +q and mass m is fired towards the centre of the sphere of velocity v from a point A at a distance r(r>R) from the centre of the sphere. Find tyhe minimum velocity v so that it can penetrate R/2 distance of the sphere.

To solve the above problem,


we can use conservation of energy.


Total initial energy = Total final energy


K.E + Initial Electrostatic P.E = Final Electrostatic P.E


K.E = (1/2)mv2


Initial E.P.E = kQq / r


Final E.P.E = kQq(3R2 - R12) / (2R3)


where k = 9 × 109 , R1 = R/2, R = radius of the non conducting sphere.


                                  r = initial seperation of the point mass from the centre of the sphere.
