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 :
Answer: (B) $27$ N
$$F = F_0\left(\frac{R}{R + h}\right)^2 = 48\left(\frac{R}{4R/3}\right)^2 = 48 \times \frac{9}{16} = 27\ \text{N}$$
