Question

What is the total external force on a system of particles when its total

momentum remains constant?​

Answer 1

Answer:

Answer. This means that P = constant. So whenever the total force acting on the system of a particle is equal to zero then the total linear momentum of the system is constant or conserved. This is nothing but the law of conservation of total linear momentum of a system of particles..

Answer 2

Explanation:

if momentum is constant,

i.e, momentum (p)=mv

where, m is mass and v is velocity

we know that mass is always a constant....

therefore, if momentum is constant, we can say that velocity is also constant...

so, if velocity is constant then external force is zero

so, external force=0
