Acceleration Due to Gravity

The height at which the weight of a body becomes $\left(\frac{1}{16}\right)$ $\text{th}$ , its weight on the surface of earth (radius R), is

Show answer and solution

Answer: (c)

$\left(\frac{R}{R+h}\right)^2 = \frac{1}{16}$
$R + h = 4R \Rightarrow h = 3R$
So the answer is (c) 3R.
