How does the acceleration due to gravity($g$) changes for the same values of height($h$) above surface of earth and depth($d$) below surface of earth?

What is Orbital velocity? Obtain an expression for it.

What is escape velocity? Obtain an expression for it.

What is geostationary satellite? State its uses.

If two places are at the same height from the sea level; one is a mountain and other one is in air. At which place will '$g$' be greater? State the reason for your answer.

The gravitational force of attraction between two objects decreases by $36\%$ when the distance between them is increased by $4 \mathrm{m}$. Find the original distance (in metres) between them.
