Question

suppose you are standing on a tall ladder height equals to the earth radius what is your weight

Answer 1

half of the height

Explanation:

because height square + radius square /2

Answer 2

Answer:F' = F/4

Explanation:

F = GMm/r^2

now gravitational force at point which is at the distance of R+R=2R (RADIUS OF EARTH + HEIGHT OF LADDER) 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.
