And those negative charges repelled one another.

Von Guericke used his generator to show that like charges repelled each other.

The repeating charges repel one another, preventing the molecule from folding into a useless clump.

According to Coulomb's interaction, negative charges repel each other.

Through continued experimentation, Maxwell determined that these charges can attract or repel each other based on their orientation.

A permanent static charge repelled the dust and kept the sheets clean.

Since positive electric charges should repel each other, why did the protons stay together?

If the airplane is made of metal, the charges repel as far away from each other as possible.

By physical understanding at that time, positive charges would repel one another and the nucleus should therefore fly apart.

Once a charge has been made, like charges will repel and unlike charges will attract.
