Question

The value of acceleration due to gravity at a depth 'd' from the surface of earth and at an altitude 'h' from the surface of earth are in the ratio

• A. 1:1
• B. $\frac{R-2h}{R-d}$
• C. $\frac{R-d}{R-2h}$
• D. $\frac{R-d}{R-h}$

Hint:

Physics Tip : Note that the altitude formula $g_h = g(1-2h/R)$ is an approximation valid only when $h$ is much smaller than the Earth's radius $R$.

Answer 1

The Correct Option is C
