Unformatted text preview: m located a distance r from the center of the earth is V g = GM e m/r . Recall that the gravitational force acting between the earth and the body is F = G ( M e m/r 2 ), Eq. 13 1. For the calculation, locate the datum at r . Also, prove that F is a conservative force. Solution: V r r G M e m r 2 d = G M e m r = QED F Grad V = r V d d = r G M e m r d d = G M e m r 2 = QED 300...
