Question

derive an expression for the gravitational potential at a 'point due to the earth
​

Answer 1

Explanation:

As E = 0, V is a constant. The value of gravitational potential is given by, V = -GM/R. Case 2: If point 'P' lies on the surface of the spherical shell (r=R): On the surface of the earth, E = -GM/R2

Answer 2

As E = 0, V is a constant. The value of gravitational potential is given by, V = -GM/R. Case 2: If point 'P' lies on the surface of the spherical shell (r=R): On the surface of the earth, E = -GM/R2.
