the below figure make small angles theta1 and theta2 with the vertical.(adsbygoogle = window.adsbygoogle || []).push({});

Figure 21-50

(a) If Q1 = Q, Q2 = 3Q, and m1 = m2 = m, determine the ratio theta1 / theta2.

(b) If Q1 = Q, Q2 = 2Q, and m1 = m, and m2 = 4m, determine the ratio of theta 1 / theta 2.

I don't get the forces that are acting on the spheres. I know there's gravitational, electrostatic, and tensional forces. How do I start the problem?
