Consider a body, shown in figure, consisting of two identical balls, each of mass M connected by a light rigid rod. If an impulse J = MV is imparted to the body at one of its ends what would be it angular velocity?

Options

A. `V//L`
B. `2V//L`
C. `V//3L`
D. `V//4L`

Explanation

By the conservation of angular momentum about `c.m.`
`MV(L)/(2)=[M((L)/(2))^(2)+M((L)/(2))^(2)]omegaimpliesomega=(V)/(L)`
