A sphere of mass M and radius R2 has a concentric cavity of radius R1 as shown in figure The force F exerted by the sphere on a particle of mass m located at a distance r from the centre of sphere varies as (0≤r≤∞) . A body attains a height equal to the radius of the earth. The velocity of the body with which it was projected is.
