does a single external force acting on a particle necessarily changes its momentum and kinetic energy

No, not necessarily.
If only one force is acting and it is perpendicular to the velocity of body, it will not change the velocity and thus, no effect on momentum or K.E.

Yes as force = change in momentum per unit time therefore force must change a body''s momentum and hennce kinetic energy.
Please approve.....

Himanshu Sharma is right, not the first one , so freind you must recheck

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.
