A body weighs 48 N on the surface of the earth. The gravitational force experienced by the body due to the earth at a height equal to one-third the radius of the earth from its surface is :

Options

  1. A16 N
  2. B27 N
  3. C32 N
  4. D36 N

Correct answer

B. 27 N

Step-by-step solution

aligned & W ^ = mg ^ = mg ( R R + h )^2 & =48 ( R R + R 3 )^2 & =48 9 16 =27 ~N aligned
