Three lead balls of mass m1 = 16kg, m2 = 26kg, and m3 = 9.3kg are arranged as shown in the figure below. Find the total gravitational force exerted by balls 1 and 2 on ball 3. Be sure to give the magnitude and the direction of this force.
direction ° counterclockwise from the +x-axis
M1 is at (1,3)
M2 is at (2.5,1)
M3 is at (4,2.5)
