A particle of mass 3m is projected from ...


A particle of mass 3m is projected from point-A with speed `3v_(0)` as shown in figure. When the particle is at point `P`, it explodes in three identical particles choose the INCORRECT statement regarding the physical quantities just before and just after explosion

A

The linear momentum of system can be conserved just before and just after explosion.

B

The centre of mass of the system will trace same path as it will follow without explosion.

C

The mechanical energy of the system remains conserved just before and just after explosion

D

The impulse given by the weight of particle during explosion is negligible as compared to that by the explosive forces.

Text Solution

Verified by Experts

The correct Answer is:
C
Weight is non impulsive force during explosion.
