A 90 ~kg body placed at 2 R distance from surface of earth experiences gravitational pull of : ( R = Radius of earth, g =10 ~m ~s ⁻² )

Options

  1. A100 ~N
  2. B300 ~N
  3. C225 ~N
  4. D120 ~N

Correct answer

A. 100 ~N

Step-by-step solution

Here g_s= gravitational acceleration at surface aligned & Value of g=g₅ (1+ h R )⁻² & =g₅(1+2)⁻²= g₅ 9 aligned Force = mg =90 g ₅ 9 =100 ~N
