There is a point b/t the Earth and the Moon where the gravitational effects of the 2 bodies balance each other. How far apart from the center of the earth is this point? Answer: x = 3.44 x 10^8 m (from the earth) or 3.82 x 10^7 m (from the moon). I have no clue what to do. I assume you would use either the equation Fg = (Gm1m2)/(r^2) or T^2 = kr^3. I really don't know what to do next. Please help.
