A weightless rod of length 2l carries two equal masses ‘m’, one tied at lower end A and the other at the middle of the rod at B The rod can rotate in vertical plane about a fixed horizontal axis passing through C . The rod of is released from rest in horizontal position The speed of the mass B at the instant rod become vertical is:
