Question

Two bodies of masses M₁ and M₂ are kept at a distance d from each other. Prove that the point at which the intensity of the gravitational field is zero, the gravitational potential will be :
V = \(\frac{-G}{d}\left[M_{1}+M_{2}+2 \sqrt{M_{1} M_{2}}\right]\)

Answer 1

Suppose the intensity of gravitational field intensity at point P is zero. Therefore, the gravitational field intensity is a vector quantity. So,
