Question

A body of mass 'm' is at rest above the ground at height 'h'. It has potential energy equal to-
1/2mgh
1/2kh^2
mgh
zero

Answer 1

Answer:

mgh

Explanation:

when any body is at rest on the surface of earth then on that body earth will exert opposite reaction on it which is equal to the wight of that body.

Here our object is at some ht. above the ground surface. So on this object there will be some restoring energy in the body which is equal to mgh.

Answer 2

Answer:

mgh is the correct answer
