A shell explodes and many pieces fly off in different directions. Which of the following is conserved?

A

kinetic energy

B

Momentum

C

Neither momentum nor `KE`

D

Momentum and `KE`

Text Solution

Verified by Experts

The correct Answer is:
B
Because during explosion of shell .`F_(ext)= 0` hence according to law of coservation of momentum `vecp_(system) =` constant
