A uniform rod of mass 200 grams and length L = 1 m is initially at rest in vertical position. The rod is hinged at the centre such that it can rotate freely without friction about a fixed horizontal axis passing through its centre. Two particles of mass m = 100 grams, each having horizontal velocity of equal magnitude u = 6 m/s strike the rod at the top and bottom simultaneously as shown, and stick to the rod. The angular speed (in rad/sec.) of the rod when it becomes horizontal is
. Write upto two digits after the decimal point.
