There are three balls A, B and C (rigid) of mass ''m'' each which are initially placed at the corners of an equilateral triangle of side length ''r'' in free space. At an instant, ball C is given a velocity tangential to the circumcircle of the triangle and the whole system is released free. For ball C to escape from the system, what should be the kinetic energy that should be given initially? Is the kinetic energy equal to the potential energy of the whole system (-3Gmm/r) or is it only equal to the potential energy between C and A; C and B (which is -2Gmm/r)??

i think it is the potential energy betwween C n A  or C n B(-2Gmm/r)
