An shaped thin uniform rod of total length is free to rotate in a vertical plane about a horizontal axis at as shown in Figure.The bar is released from rest. Neglect air and contact friction. Determine the angular velocity (in rad/s) at the instant when it has rotated through and reached the dotted position as shown. (Take 1/3m)
