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
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

Solution:
The correct option is c) m will move towards 2M
