Beads \( A \) and \( B \), each of mass \( m \), are connected by a light inextensible cord. They are constrained (restricted) to move on a frictionless ring in a vertical plane as shown. The beads are released from rest at the positions shown. The tension in the cord just
\( \mathrm{P} \) after the release is
(1) \( \sqrt{2} \mathrm{mg} \)
(2) \( m g \)
(3) \( \frac{1}{\sqrt{2}} m g \)
(4) \( 2 m g \)
