Q one, the charge of atom one and q two, the charge of atom two. And the denominator is simply the square, the distance between the center of masses of those two charges. So we see that the larger the charge is, the greater the numerator is and the greater the tractive force is. And likewise, the smaller our separation distance is, the closer our two charges are, the smaller our denominator is and the greater the electrostatic force is. Now, the thing about electric force is it's not only attractive in nature, but it can also be repulsive in nature. For instance, if we have two light charges.
