A body weighs $72 N$ on the surface of the earth. What is the gravitational force on it, at a height equal to half the radius of the earth?

Answer:

Solution:

$W_{s} = m g_{s} = 72 N$

$W_{h} = m g_{h} = \frac{m g_{s}}{{(1 + \frac{h}{R})}^{2}} = \frac{72 N}{{(1 + \frac{R / 2}{R})}^{2}} = \frac{72}{9 / 4}$

$W_{h} = 32 N$
