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
${W_1} < {W_2} > {W_3}$
${W_1} = {W_2} = {W_3}$
${W_1} < {W_2} < {W_3}$
${W_1} > {W_2} > {W_3}$
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
Because value of g decreases when we move either in coal mine or at the top of mountain.
