The height of any point P above the surface of earth is equal to diameter of earth. The value of acceleration due to gravity at point P will be : (Given g = acceleration due to gravity at the surface of earth).

Options

  1. Ag 2
  2. Bg 4
  3. Cg 3
  4. Dg 9

Correct answer

D. g 9

Step-by-step solution

Acceleration due to gravity at a height h from the surface of the Earth, g ' = g 1 1 + h R 2 Given: h = 2 R ∴ g ' = g 1 1 + 2 2 or g ' = g 9
