Consider two identical balls. One is hanging on a spring scale in the laboratory, and one is hanging on a spring scale 50 km above the surface of the Earth. Which ball weighs more

g decreases with the increase in height hence the ball hanging above 50 Km above the surface will show less wight.

Explanation: Acceleration due to gravity that we consider 9.8 (approx) varies with the height and depth.

As we go above the sea level the value of g decreases and follows the relation:

is the acceleration due to gravity at height h Km

is the acceleration due to gravity at sea level i.e 9.8

R is the mean radius of earth i.e. 6378 km at the equator & 6357 km at pole.

h is he height where you wants to calculate the g.

Weight is defined as the pull force exerted on an object by earth's gravity.

Weight = mass acceleration due to gravitational

W = mg

So, weight depends on the acceleration due to gravity. g decreases with the increase in height hence the ball hanging above 50 Km above the surface will show less wight.
