Problem
Two identical pendulums, A and B, are suspended from the same point. The bobs are given positive charges, with A having more charge than B. They diverge and reach equilibrium, with A and B making angles θ1 and θ2 with the vertical respectively.
(a) θ1>θ2
(b) θ1<θ2
(c) θ1=θ2
(d) The tension in A is greater than that in B
