How can an unbalanced force exist if every action has an equal and opposite reaction?

Question

How can an unbalanced force exist if every action has an equal and opposite reaction?

Answer 1

equal and opposite reaction acts on another body

Answer 2

If you look at a free body diagram of a particle that has a force acting on it in one direction, and that is the only force, then this is "unbalanced" and the particle will accelerate. What you are thinking of (Newton's Law) means that whatever object is applying that force to that particle, whether it is another particle colliding with particle 1, or a charged object applying a coulomb force to particle 1, will feel a force on it in reaction to the force it is applying on particle 1. But this reactionary force is not a force exerted on particle 1, but a force exerted by particle 1, which cannot affect its own (particle 1's) motion.

Answer 3

See Newton's third law clearly states that

"Every action has an equal and opposite reaction"

So here it isn't mentioned on the same body...so unbalanced forces can exist, Coz action and reaction are sets of forces acting on DIFFERENT bodies.
