Solution

The correct option is A $d = 2 k m$
Acceleration due to gravity at height h,
$g_{h} = g_{0} (1 - \frac{2 h}{R})$
Acceleration due to gravity at depth d,
$g_{d} = g_{0} (1 - \frac{d}{R})$
$g_{h} = g_{d}$
$g_{0} (1 - \frac{2 h}{R}) = g_{0} (1 - \frac{d}{R})$
$d = 2 h$
$d = 2 \times 1 k m$
$d = 2 k m$
