when external force on a system is zero than linear momentum of system remains conserved.
because force is change in momentum per second
F = dP/dt
If F = 0
Then dP = 0
so P = constant
Hope it clears.

F=m.a ( Here F is only stands for external force)
F=m.(v-u)/t
if v=u then F=0 & if v=u then momentum, pi=mu ,pf=mv is also equal.
change in momentum= pf – pi =0
hence momentum is constant in absence of external force.

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
