1. The problem statement, all variables and given/known data I'm stuck at one of my homework questions.Basically,it says there is a line EM between the earth's and moon's centre of masses.The moon revolves around the earth in circular motion.Point X(somewhere in between moon and earth)represents a point where the resultant gravitational force is 0.Mass of moon/Mass of earth=0.012. Given distance EX is 3.4x10^8,determine distance of EM. Sorry I can't show a diagram. 2. Relevant equations F=GMm/r^2 I can only think of this. 3. The attempt at a solution It's quite lengthy and after some time I realised it was wrong so I think it would be better if I just read some suggested solutions from you guys.
