A man of weight $W$ on the surface of the earth. What is his weight at a height equal to $R$ ?

Options:

Answer:

Solution:

Value of g at height h is given as $g_{e f f} = \frac{g}{{(1 + \frac{h}{R})}^{2}}$

$\frac{W_{h}}{W} = \frac{m g_{h}}{m g}$

$= \frac{g_{h}}{g}$

$= \frac{R^{2}}{{(R + R)}^{2}}$

$W_{h} = \frac{W}{4}$
