Explain how the force of electric interactions is related to the force of magnetic interactions.

Explanation:

An electric force is a force of attraction or repulsion between charged particles, which have unequal numbers of protons and electrons.

Similar to electric charges, opposite poles attract, and like poles repel. The stronger the magnets and the closer together they are, the stronger the magnetic force between them.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
