Two particles, A and B of masses M1 and M2 respectively, experience a mutual gravitational attraction. Show that the acceleration of A towards be is independent of the mass of particle A.

Comes right out of applying Newton's third laws F = ma to the case of gravitational force: F = GmM/d^2.

Thank you :) I managed to do it.

F_G=\frac {GmM}{R^2}
