Taking the radius of the earth to be $6400 km$ , by what percentage will the acceleration due to gravity at a height of $100 km$ from the surface of the earth differ from that on the surface of the earth?

Options:

Answer:

Solution:

Acceleration due to gravity at a height $h$ from the surface of the earth is $g_{h} = \frac{g R ^{2}}{( R + h ) ^{2}}$ where $g$ is the acceleration due to gravity on the surface of the earth and $R$ is the radius of the earth.
