(a) Three 0.3 kg billiard balls are placed on a table at the corners of a right triangle, as shown from overhead in the figure, with distances r13 = 0.325 m, r12 = 0.415 m, and r23 = 0.527 m. Find the magnitude of the net gravitational force on the cue ball (designated as m1) resulting from the forces exerted by the other two balls.
___N?
(b) Find the components of the gravitational force of m2 on m3. (Indicate the direction with the sign of your answer.)
F23x = ___ N (c) Find the magnitude and direction of the force exerted by m1 and m3 on m2.
