Pseudo Force

A uniform rod...

Question

A uniform rod PQ of mass m and length l rotates with an angular vel. ω while its centre moves with linear vel. v=2ω l/3 on a smooth horizontal surface. If the end Q of the rod is suddenly gets stuck at the moment , then angular vel. of the rod will be ( ω is in anticlockwise direction about the centr of the rod and its P end is downwards and Q end upwards)-
