Stаr A оf mаss 300.00 kg is аt x=0.00 m, y=0.00 m and star B оf mass 600.00 kg is at x=0.00 m, y=2.00 m, as shоwn in Fig. 3.1. (a) What are the direction and magnitude of the gravitational force on star B exerted by star A? Place a particle of mass M on the y-axis. (b) Is there a point on the y-axis at which the net gravitational force exerted by both A and B on it is zero, and if so, where is it? (c) If star B moves around star A, what is star B's orbital speed? (d) If star C of mass 500.00 kg is at x=2.00 m, y=0.00 m as shown in Fig. 3.2, (d) what is the magnitude and (e) what is the direction of the net gravitational force on star C exerted by both stars A and B?
