The value of gravitational acceleration $g$ at a height $h$ above the earth's surface is $\frac{g}{4}$ then (R = radius of earth)

Options:

Answer:

Solution:

$g^{'} = g {(\frac{R}{R + h})}^{2}$
When $g^{'} = \frac{g}{4}$ then.
$\frac{g}{4} = g \times {(\frac{R}{R + h})}^{2} \Rightarrow \frac{1}{2} = \frac{R}{R + h}$
$∴ 2 R = R + h \Rightarrow R = h$
