Ball A attached to one end of a rigid massless rod while identical ball B is attached to centre of rod. Each ball has a mass of 0.5 kg and length of each half of 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, n tension on left of rod is
