According to newtons first law, an object in motion will stay in motion unless:

A5 nc point charge is at the origin and a second 3 nc point charge is on the x-axis at x = 0.8 m. find the magnitude and direction of the electric field on the x-axs at x = 0.2 m. you may express the direction by letting positive field mean the positive x direction

What happens to atoms and chemical bonds during a reaction?
