Question

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 is released from rest in horizontal position. The speed of the mass B at the instant rod, become vertical is

Q. A weightless rod of length 2l carries two equal masses 'm', one secured at lower end A and the other at the middle of the rod at B. The rod can rotate in verticle plane about a fixed horizontal axis passing through C. What horizontal velocity must be imparted to the mass at A so that it just completes the vertical circle.
