There are two masses both M +a and -a apart with respect to the origin on the y axis. A third mass, m, is x away from the origin. Due to gravity it will oscillate back and forth. What is T(adsbygoogle = window.adsbygoogle || []).push({});

Also, how can I use conservation of energy to find the velocity of the third mass m when it reaches the origin if it started at rest?

so far i got

g=2Gmx/(x^2+a^2)^(3/2)

and for the conservation of energy the PEi has to equal KEf
