Acceleration due to gravity and its variation

Question

The weight of an object in the coal mine, sea level, at the top of the mountain are $W_{1}, W_{2} a n d W_{3}$ respectively, then

Easy

A

$W_{1} < W_{2} > W_{3}$
B

$W_{1} = W_{2} = W_{3}$
C

$W_{1} < W_{2} < W_{3}$
D

$W_{1} > W_{2} > W_{3}$

Solution

$g_{d} = g (1 - \frac{d}{R}) \Rightarrow g_{h} = g (1 - \frac{2 h}{R}) = = g (1 - \frac{2 d}{R}) i f h = d \Rightarrow g_{h} < g_{d}$
Because value of g decreases when we move either in coal mine or at the top of mountain.
