Question 320: Gravitation

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

Accepted Answer

$$\begin{aligned}
& \frac{g_d}{g_h}=\frac{g\left[1-\frac{d}{R}ight]}{g\left[1-\frac{2 h}{R}ight]} \
& \frac{g_d}{g_h}=\frac{R-d}{R-2 h}
\end{aligned}$$

Answer

$$1: 1$$

Answer

$$\frac{R-2 h}{R-d}$$

Answer

$$\frac{R-d}{R-2 h}$$

Answer

$$\frac{\mathrm{R}-\mathrm{d}}{\mathrm{R}-\mathrm{h}}$$
