The magnitude of gravitational potential energy at a distance r from the centre of earth is U, then show the weight at this point in the form of U.

The magnitude of gravitational potential energy at a distance r from t

1.	The magnitude of gravitational potential energy at a distance r from the centre of earth is U, then show the weight at this point in the form of U.
Answer» Solution :`U=(Gm_em)/R=((Gm_e)/r^2)MR = gmr ` `:. mg =U/r`
