Can someone please tell me the derivative of the following with respect to little 'r' where G is the gravitional constant (6.67x10^-11), Me is mass of earth (5.98X10^24kg), Ms is mass of a spacecraft that has a mass of 1000kg and R which is the distance between the earth and the moon (384400 x 10^3m). Thanks.(adsbygoogle = window.adsbygoogle || []).push({});

U = (-GMeMs)/(r) - (GMmMs)/(R-r)
