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).
  1. g2
  2. g4
  3. g3
  4. g9

Solution

Acceleration due to gravity at a height h from the surface of the Earth,
g'=g11+hR2
Given: h=2R
∴g'=g11+22
or g'=g9
