Question

The weight of an object in the coal mine, sealevel, at the top of the mountain are W1, W2 &W3 respectively, then

Answer 1

Answer:

W1<W2>W2

Explanation:

Weight = mass*gravitational acceleration(g)

At Sea Level

g = GM(earth)/r²

At Coal mine

g = g(surface)(1-(x/r))            where x is distance below the surface of earth

At mountain

g = g(surface)(1-(2x'/r))         where x' is small distance above earth's surface

Thus for non zero values of x and x' W1<W2>W3
