Considering earth to be a sphere of radius ' R ' having uniform density ' ', then value of acceleration due to gravity ' g ' in terms of R, and G is

Options

  1. Ag = 3 R G
  2. Bg= 4 3 GR
  3. Cg = 4 3 GR
  4. Dg = GM R ^2

Correct answer

C. g = 4 3 GR

Step-by-step solution

g = GM R ^2 = G 4 3 R ^3 R ^2 = 4 3 GR
