The gravitational potential energy of a body of mass ‘m’ at the earth’s surface is –mgRe. Its gravitational potential energy at a height Re from the earth surface will be (Re is the radius of earth)
-2mgRe
2mgRe
1/2 mgRe
-1/2 mgRe
As we learn
Work done against gravity -
work done
change in Potential energy
distances
- wherein
If body is moved from surface of earth to a point above surface of earth then use the given formula
as h = Re
