The acceleration due to gravity ' g ' for objects on or near the surface of earth is related to the universal gravitational constant ' G ^ as ('M' is the mass of the earth and ' R ' is its radius):

Options

  1. AG=g M R^2
  2. Bg=G M R^2
  3. CM = gG R ^2
  4. DR = gG M ^2

Correct answer

B. g=G M R^2

Step-by-step solution

g = GM / R ^2
