The height above the surface of the earth where acceleration due to gravity becomes ( g 9 ) is ( R is radius of the earth, g is acceleration due to gravity)

Options

  1. A2R
  2. BR 3
  3. CR 2
  4. D2 R

Correct answer

A. 2R

Step-by-step solution

aligned & g^ = g (1+ h R )^2 & g 9 = g (1+ h R )^2 & h=2 R aligned
