Acceleration Due to Gravity

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:

Show answer and solution

Answer: (d)

  1. Wh=W(1+h/R)2W_h = \frac{W}{(1 + h/R)^2} with h=R3h = \frac{R}{3}.
  2. Wh=48(4/3)2=48×916W_h = \frac{48}{(4/3)^2} = 48 \times \frac{9}{16}
  3. Wh=27 NW_h = 27\ \text{N}
  4. So the answer is (d) 27 N.
