Two very small balls A and B of masses 4.0 kg and 5.0 kg are affixed to the ends of a light inextensible cord that passes though a frictionless ring of radius negligible compared to the length of the cord. The ring is fixed at some height above the ground. Ball A is pulled aside and given a horizontal velocity so that it starts moving on a circular path parallel to the ground, keeping ball B in equilibrium as shown.
