Question

suppose you are standing on a tall ladder.If your distance from the centre of the earth is 2R,what will be your weight?

Answer 1

we know that
gravitation force = GMm/r^2. (at the surface of the earth)

F = GMm/r^2

now gravitational force at point which is at the distance of 2R from the center or Earth will be

F' = GMm/(2R)^2

F' = GMm/4R^2

F' = [GMm/R^2] × 1/4

F' = F/4

so the appearant weight at this distance will be 1/4 th of the weight at the surface of earth.
