Objects \( \mathrm{A} \) and \( \mathrm{B} \) each of mass \( m \) are connected by light inextensible cord. They are constrained to move
P on a frictionless ring in a vertical plane as shown in

W figure. The objects are released from rest at the positons shown. The tension in the cord just after release will be
(1) \( m g \sqrt{2} \)
(2) \( \frac{m g}{\sqrt{2}} \)
(3) \( \frac{m g}{2} \)
(4) \( \frac{m g}{4} \)
