For every action, there is an equal and opposite reaction. If the action and reaction forces are always equal and opposite, why don't they always cancel to zero? How is it possible for net force on an object to be non-zero?

Two forces equal in magnitude and opposite in direction, acting on an object at two different points, form what is called a couple. Two antiparallel forces with equal magnitudes_1 = F_2 =7.90 N are applied to a rod as shown in the figure (Figure1). What should the distance l between the forces be if they are to provide a net torque of 5.20 N m about the left end of the rod? Is the sense of this torque clockwise or...

If a magnetic field and an electric field are pointing in opposite directions, how can the net force (electric plus magnetic) on an electron be equal to zero? Answer: It is not possible for the net force to be zero My question is why is this the case? I am having troubling conceptualizing it.
