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

A

Both of them have equal speeds

B

Both of them move along a same line with unequal speeds

C

Sum of their momentum is non zero

D

They move along different lines with different speeds

Text Solution

Verified by Experts

The correct Answer is:
B
`m_1v_1 + m_2v_2 =0`
`implies m_1v_1 =-m_2 v_2 ` (along same line).
