How does the weight ofa bodyvarywhile moving from the earth to the moon ?

Options

A. It graduaily decreases till it reaches the moon surface
B. It gradually increases till it reaches the moon surrace.
C. First it gradually decreases to zero value and then increases till it reaches the moon surface
D. First it gradually increases and then decreases till it reaches the moon surface.

Answer

C

Explanation

The weight W of a body is given by, W = mg Where m is the mass of the body which remains constant everywhere and g is the acceleration due to gravity which varies as the place where the body is available.
On moving upwards from earth surface, g gradually decreases and becomes zero where the forces of attraction of earth and of moon cancel each other. This results that the weight ofbody is zero. Further, moving to the moon, g gradually increases till it reaches the moon surface.
