Sahay Sir > Question Answers > Three identical bodies (each mass M) are placed at vertices of an equilateral triangle of arm L
A solid sphere of lead has mass M and radius R. A spherical hollow is dug out from it(see Figure). Its boundary passing through the centre also touches the boundary of the solid sphere. Deduce the gravitational force on a mass m placed at P, which is at a distance r from O along the line of centres.
