Question

Object A and B each of mass $m$ are connected by light inextensible cord. They are constrained to move on a frictionless ring in a vertical plane as shown in figure. The objects are released from rest at the positions shown. The tension in the cord just after release will be

$m g \sqrt{2}$
$\frac{m g}{\sqrt{2}}$
$\frac{m g}{2}$
$\frac{m g}{4}$

The correct answer is: $fraction numerator m g over denominator square root of 2 end fraction$

Figure shows an arrangement of a rod of length l and mass M and a bead of mass m attached to a weightless string passing over a frictionless pulley. At t=0, the bead is in level with the lower end of the rod. The bead slides down the string with considerable friction and is opposite the other end of the rod after $t$ second. Assuming friction between the bead and the string to be constant all through, the frictional force is
