The Planet Alpha (‘Alpha’) has the mass of M.
Alpha has a Moon Beta (‘Beta’) whose mass is 0.05M.
The mean difference between Alpha and Beta is R.
An asteroid is at point ‘x’ exactly ¼ away from Alpha in a straight line between the centres of Alpha and Beta: Calculate the value of the ratio:
Force exerted on asteroid by Alpha?
Force exerted on asteroid by Beta?
At what distance, expressed in terms of R, from Alpha, along a straight line joining the centres of Alpha and Beta, will the ratio expressed in part a be equal to 6400?
Point Y represents the distance from Alpha where the magnitude of the net gravitational force is zero. What is the distance in terms of R?
