A point mass m is released from rest at a distance of 3R from the centre of a thin walled hollow sphere of radius R and mass M as shown. The hollow sphere is fixed in position and the only force on the point mass is the gravitational attraction of the hollow sphere. There is a very small hole in the hollow sphere through which the point mass falls as shown. The velocity of point mass when it passes through point P at a distance R/2 from centre of sphere, is
