Three particles bodies of mass M are located at the vertices of an equilateral triangle of side L they revolve under the effect of mutual gravitational force in circles circumscribing the triangle the speed of each body?

 

Now, the necessary centripetal force is provided by the net force due to the three stars.Thus, inside the equilateral triangle. The distance from the center of its orbit is given byOFrom the figure, the stars orbit about a point The position of the three stars which are located at the vertices of an equilateral triangle is shown below. RegardsArun (askIITians forum expert)
