Physics - Rotation Question with Solution | TestHub

A uniform rod of mass m and length $2\ell$ lies on smooth horizontal surface. A particle of same mass m is connected to string of length $\ell$, whose other end is connected to rod. Initially string is taut and both rod and string lies in same horizontal plane with 90° angle between them. If particle is given initially velocity ${\mathrm{v}}_0$ perpendicular to string, then just after giving velocity ${\mathrm{v}}_0$ to particle :-
