51 A solid sphere of uniform density and mass M has radius 4 m Its centre is at the origin of the coordinate system Two spheres of radii 1 m are taken out so that their centres are at P 0 2 0 and Q 0 2 0 respectively This leaves two spherical cavities What is the gravitational field at the origin of the coordinate axes 1 31GM 1024 3 31GM 52 In problem 51 what is the gravitational field at the centre of the cavities 31GM 1 1024 1 2 Gm 1024 4 Zero GM Gm 1024 3 31GM 53 In problem 51 what is the gravitational potential at any point on the circle x 6 2 2 4 GM GM 64 10 CH
