Question

Which of the following must be true for momentum to be conserved in a system of interacting particles?

There is no net external force acting on the particles, and the force of interaction between the particles is conservative.

There is no net external force acting on the particles.

There are no external forces acting on the particles.

There is no external force acting on the particles, and the force of interaction between the particles is conservative.

There is no net external force acting on the particles, and the force of interaction between the particles is conservative.

There is no net external force acting on the particles.

There are no external forces acting on the particles.

There is no external force acting on the particles, and the force of interaction between the particles is conservative.

Explanation / Answer

For momentum to be conserved in a system of interacting particles, no external forces must act on the system. But force of interaction between particles need to be or need not to be conservative.

Hence correct option: There are no external forces acting on the particles.
