AB is a mass less rigid rod of length 2l. It is free to rotate in vertical plane about a horizontal axis passing through its end A. Equal point masses (m each) are stuck at the centre C and end Bof the rod. The rod is released from horizontal position. Write the tension in the rod when it becomes vertical.
