consider two bodies A and B of equal masses.Suppose thatthe body A is on the ground and the body Bis ata height h above the ground.What can you say about the difference in the gravitational potential energies of the two bodies? please explain

Answer 1

Since this is not my area of expertise, I searched Google under the key words "'gravitational potential energies' mass altitude" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
