The height vertically above the earth's surface at which the acceleration due to gravity becomes $1%$ of its value at the surface is ( $R$ is the radius of the Earth)

Options:

Answer:

Solution:

$Hints : g^{'} = \frac{g}{( 1 + \frac{h}{R} ) ^{2}} \Rightarrow \frac{g}{100} = \frac{g}{( 1 + \frac{h}{R} ) ^{2}} 1 + \frac{h}{R} = 10 \Rightarrow \frac{h}{R} = 9, h = 9 R$
