Stаr A оf mаss 300 . 00 k g is аt x = 0 . 00 m , y = 0 . 00 m and star B оf mass 600 . 00 k g is at x = 0 . 00 m , y = 2 . 00 m , as shоwn in Fig. 3.1 (see the attached doc file). (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 k g is at x = 2 . 00 m , y = 0 . 00 m as shown in Fig. 3.2 (see the attached doc file), (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? test2_q13.v01.docx
