In the arrangement shown in the figure-1.132, if $v_{1}$ and $v_{2}$ are the instantaneous velocities of masses $m_{1}$ and $m_{2}$ respectively, and angle $A CB = 2 θ$ at the instant, then:

Options:

Answer:

Solution:

By the string constraint, each side string shortens at the rate $v_{1} cos θ$ along its length, and $v_{2} = 2 v_{1} cos θ$ . Hence $θ = cos^{- 1} \frac{v _{2}}{2 v _{1}}$ . Option A.
