Final answer:
Two particles that have opposite charges (one + and the other -) will attract each other. Opposite charges attract each other according to Coulomb's findings. Examples include electrons being attracted to protons.
Step-by-step explanation:
Two particles that have opposite charges (one + and the other -) will attract each other.
Opposite charges attract each other, according to Coulomb's findings.
Just like the N and S poles of magnets attract each other, particles with opposite charges are drawn towards each other.
For example, electrons, which are negatively charged, are attracted to protons, which are positively charged.
