                  Particles of masses 2M, m and M are respectively at points A, B and C with \[AB=1/2\,(BC)\]. m is much-much smaller than M and at time t = 0, they are all at rest                 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.

Answer:

                  (c) Gravitational force between 2M and m is greater than the gravitational force between M and m.
