Dynamics- Net Gravitational Force

Click For Summary
SUMMARY

The discussion focuses on calculating the location of the point in a binary star system where the net gravitational force is zero. Star A has a mass 28 times that of Star B, and the distance between the stars is 34 AU. To find the equilibrium point, one must assume an arbitrary point between the two stars and calculate the gravitational forces exerted by each star at that point. The solution involves applying the gravitational force formula FG = Gm1m2/r² to determine where these forces balance out.

Homework Statement


In a particular binary star system, Star A has a mass that is 28 times that of Star B. This distance between the stars is 34 AU (astronomical units). Find the location of the point in this star system where the net gravitational force on any mass would be zero.


Homework Equations



FG = Gm1m2
r2

The Attempt at a Solution



I have no idea on this one, if someone could explain how the information is even relevant and how I;m supposed to be solving it

Assume an arbitrary point between the two stars which has net gravitational force zero.
Then calculate the force exerted on that point by each star. Then you can use the information that the "net gravitational force on any mass would be zero".You should get the answer:smile:

If doubts post again:smile:
