A particle of mass M is situated at the centre of a spherical shell of same mass and radius a. The gravitational potential at a point situated at a/ 2 distance from the centre, will be

Options

  1. A- 3 G M a
  2. B- 2 GM a
  3. C- GM a
  4. D- 4 GM a

Correct answer

A. - 3 G M a

Step-by-step solution

Gravitational potential at point a/2 distance from centre aligned & =- GM a - GM a / 2 & =- 3 GM a aligned
