Two identical pendulums, A and B, are suspended from the same point. T

1.	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.
Answer» Correct Answer is: (c) θ₁ = θ₂ Equal electrostatic forces act on both the bobs. The weights are also the same. Hence, they have identical free-body diagrams.

Correct Answer is: (c) θ₁ = θ₂

Equal electrostatic forces act on both the bobs. The weights are also the same. Hence, they have identical free-body diagrams.
