Ball A attached to one end of a rigid massless rod while the identical ball B is attached to the centre of the rod. Each ball has a mass of 0.5 kg and the length of each half of the rod is 0.4 metre. This arrangement is held by an empty end and is whirled around in a horizontal circle at a constant rate so each ball is in uniform circular motion. Ball A travels at a constant speed of 4 metre per second, then the tension on the left of the rod is
