A body is taken to a height of $n R$ from the surface of the earth. The ratio of the acceleration due to gravity on the surface to that at the altitude is

Options:

Answer:

Solution:

Aceleration due to gravity at a height $h$ above the earth surface $g^{'} = g (\frac{R}{R + h})^{2}$ $\frac{g}{g ^{'}} = (\frac{R + h}{R})^{2} \frac{g}{g ^{'}} = (\frac{R + n R}{R})^{2} \frac{g}{g ^{'}} = (1 + n)^{2}$
