The gravity potential energy is maximum at

Options

  1. AInfinity
  2. Bthe earth's surface
  3. Cthe centre of the earth
  4. Dtwice the radius of the earth

Correct answer

A. Infinity

Step-by-step solution

The gravitational potential energy is the energy possessed by a mass because of its position in a gravitational field. The expression for gravitational potential energy for bringing a mass m   near the mass M   is U = - G M m r   here r   is the distance between the mass M   and   m Since, U ∝ - 1 r   therefore, the gravitational potential energy is maximum at r = ∞
