1. The problem statement, all variables and given/known data 2 small spheres of charge "q" suspended from strings of length "l" are connected at a common point. one sphere has mass m, the other 2m. Assume angles theta_1 and theta_2 that strings make with vertical are small. (a) how are theta_1 and theta_2 related? (b) show that the distance r btw spheres is (3k*q^2*l/(2mg))^(1/3) 2. Relevant equations Refer to question 3. The attempt at a solution My attempt involved taking the cos and sin of both angles and getting particular geometric lengths. Ultimately, from these I got the angle from the horizontal that the higher ball is at with respect to the lower ball. I won't list this here as this is largely a dead end. It would be far too hard to separate theta 1 and theta 2 in the component eqns. The math should be far easier than this considering all the other questions were much simpler (and this is only question 3 of 7). My guess is I can use the approximation somewhere. Assuming that the 2 balls are roughly on the same horizontal plane makes for an easy solution (angle1 = 2*angle 2), but I was hesitant to employ this particular approximation. I realize this question is more complicated, so I hope there are any takers out there.
