Q. If $g_{e},\ g_{h}$ and $g_{d}$ be the accelerations due to gravity at earth’s surface, a height $h$ and at depth $d$ respectively. Then

A) $g_{e} > g_{h} > g_{d}$
B) $g_{e} > g_{h} < g_{d}$
C) $g_{e} < g_{h} < g_{d}$
D) $g_{e} < g_{h} > g_{d}$
Explanation

(b) When going above at a height $h$ or at a depth $d$ below earth’s surface, in any case acceleration due to gravity decrease. Therefore,
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ g_{e} > g_{h}\ and\ g_{e} > g_{d}$
$Moreover\ \ \ \ \ \ \ g_{h} < g_{d},\ if\ h = d$.
