Question

the gravitational potential energy of a body of mass m is 10 power 7 J.What minimum energy is required to protect the body out of gravitational field of the earth​

Answer 1

Answer:

I can't understand your question

Answer 2

Answer:

The change in gravitational potential energy, ΔPEg, is ΔPEg = mgh, with h being the increase in height and g the acceleration due to gravity.

The gravitational potential energy of an object near Earth’s surface is due to its position in the mass-Earth system. Only differences in gravitational potential energy, ΔPEg, have physical significance.
