Vedclass · Answer

(D) The acceleration due to gravity $(g)$ at a height $(h)$ above the Earth's surface is given by $g_h = g(1 - 2h/R)$,where $R$ is the radius of the Earth. As $h$ increases,$g_h$ decreases.Similarly,the acceleration due to gravity at a depth $(d)$ below the Earth's surface is given by $g_d = g(1 - d/R)$. As $d$ increases,$g_d$ decreases.Therefore,for both scientist $A$ (moving deep into a mine) and scientist $B$ (moving high up in a balloon),the measured acceleration due to gravity decreases.

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 acceleration due to gravity as measured by:
