(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 = 0.320 m, r12 = 0.375 m, and r23 = 0.493 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
F23y = ????N

The drawing shows two identical systems of objects; each consists of the same three small balls connected by massless rods. In both systems the axis is perpendicular to the page, but it is located at a different place, as shown. The same force of magnitude F is applied to the same ball in each system (see the drawing). The masses of the balls are m1 = 9.4 kg, m2 = 6.9 kg, and m3 = 7.2 kg. The magnitude of...
