1. The problem statement, all variables and given/known data The average distance separating Earth and the moon is 384000km. What is the net gravitational force exerted by Earth and the moon on a 3.00 x 10^4kg spaceship located halfway between them. 2. Relevant equations F=Gm1m2/r^2 G = 6.673x10^-11 earth mass = 5.98x10^24 moon mass = 7.36x10^22 3. The attempt at a solution I found the force exerted by the earth on the spaceship and then the force exerted by the moon on the spaceship. Did I do that right? Please help, this is one of my non-favorite topics. thanks!
