The value of acceleration due to gravity at a height of 4 R_E from surface of earth is R_E is radius of earth and acceleration due to gravity on the surface of the earth = 10 ~ms ⁻² )

Options

  1. A0.2 ~ms ⁻²
  2. B0.3 ~ms ⁻²
  3. C0.4 ~ms ⁻²
  4. D3 ~ms ⁻²

Correct answer

C. 0.4 ~ms ⁻²

Step-by-step solution

Acceleration due to gravity ' g ' varies with height as g^ =g ( R R+h )^2 Given R + h =5 R and g =10 ~m / s ^2 g^ =10 ( R 5 R )^2= 10 25 =0.4 ~m / s ^2
