3 Start rotating around earth in a circular orbit 4 Escape from gravitational field of earth Gravitational field intensity 33 A uniform sphere of mass M and radius R is surrounded by a concentric spherical shell of same mass but radius 2R A point mass m is kept at a distance x R in the region bounded by spheres as shown in the figure The net gravitational force on the particle is 1 2 GMm x GMmx R G M m x 3 4 Zero M R m 2R M
