Acceleration Due to Gravity

A body of weight 72 N moves from the surface of earth at a height half of the radius of earth, then gravitational force exerted on it will be

Show answer and solution

Answer: (b)

  1. Wh=W(1+h/R)2W_h = \frac{W}{(1 + h/R)^2} with h=R2h = \frac{R}{2}.
  2. Wh=72×49=32 NW_h = 72 \times \frac{4}{9} = 32\ \text{N}
  3. So the answer is (b) 32 N.
