The gravitational field a distance r inside a spherical cloud of radius R and total mass M is given by g = - GN M „2 R' where GN is Newton's gravitational constant. The gravitational potential, , at a point r < Rinside the cloud, relative to infinity is given by the g expression GyM (3 -R) What is a ?
