Particles of masses 2M, m and M are respectively at points A, B and C with AB = ½ (BC). m is much-much smaller than M and at time t = 0, they are all at rest (Fig. 8.1). At subsequent times before any collision takes place:
(a) m will remain at rest.
(b) m will move towards M.
(c) m will move towards 2M.
(d) m will have oscillatory motion.
