Q. The weight of an object in the coal mine, sea level, at the top of the mountain are $W_{1},\ W_{2}$ and $W_{3}$ respectively, then
A) $W_{1} < W_{2} > W_{3}$
B) $W_{1} = W_{2} = W_{3}$
C) $W_{1} < W_{2} < W_{3}$
D) $W_{1} > W_{2} > W_{3}$
Explanation
(a) Because value of $g$ decreases when we move either in coal mine or at the top of mountain
