Question

Two particles each of mass m are attached at the ends of a massless rod of length L which is on a smooth table at rest. An impulse J is applied to one particle along a direction perpendicular to the length of the rod. Immediately after that , angular velocity of the rod would be

$\frac{J}{m L}$
$\frac{2 J}{m L}$
$\frac{J}{2 m L}$
$\frac{2 J}{3 m L}$

The correct answer is: $fraction numerator J over denominator m L end fraction$
