1 28 A positive charge Q is uniformly distributed throughout the volume of a dielectric sphere of radius R A point mass having charge q and mass m is fired towards the centre of the sphere with velocity v from a point at distance x from the centre of the sphere Find the minimum velocity v so that it can penetrate R 2 distance of the sphere Neglect any resistance other than electric interaction Charge on the small mass remains constant throughout the motion 71 2 Ans 2KqQ r mR R 3 r 8
