A body at rest breaks into two pieces of equal masses. The parts will move

A

Be at rest

B

Move with different velocities in different directions

C

Move with the same velocity in opposite directions

D

Move with the same velocity in same direction

Text Solution

Verified by Experts

The correct Answer is:
C
Law of conservation of momentum
`m_1v_1 = m_2v_2 implies mv_1 = mv_2 implies v_1 = v_2`.
