Two objects A and B, each of mass m, are connected by a light inextensible string. They are restricted to move on a frictionless ring of radius R in a vertical plane (as shown in the figure). The objects are released from rest at the position shown. Then the tension in the cord just after release is

Detailed Solution

As shown in Figs. (a) and (b) from FBD of A,

$T \cos 45^{\circ} = m a . . . . . . (i)$

From FBD of .B:

$M g - T \cos 45^{\circ} = m a . . . . . (i i)$

From (i) and (ii), we get $T = m g / \sqrt{2}$
