NEET Physics Question - Gravitation - Acceleration Due to Gravity and its variation

Consider earth to be a homogeneous sphere. Scientist A goes deep down in a mine and scientist B goes high up in a balloon. The value of g measured by:

A goes on decreasing and that by B goes on increasing

B goes on decreasing and that by A goes on increasing

Each decreases at the same rate

Each decrease at different rates

Solution:

Acceleration due to gravity decreases with depth as \( g_d = g(1 - \frac{d}{R}) \) and with height as \( g_h = g(1 - \frac{2h}{R}) \). Since the formulas and rates of decrease are different, they decrease at different rates.
