Final answer:
The force that causes an electron to be quickly pushed away from another electron is the electromagnetic force. It is responsible for holding atoms together and creating stable orbits for electrons around the nucleus.
Step-by-step explanation:
The force that causes an electron to be quickly pushed away from another electron is the electromagnetic force (Option A). The electromagnetic force is the force of attraction or repulsion between electrically charged particles. In this case, the negative charge of one electron repels the negative charge of another electron, causing them to be pushed apart.
Unlike the other forces listed, such as gravity, strong nuclear force, and weak nuclear force, the electromagnetic force can act over long distances and is much stronger compared to gravity. It is responsible for holding atoms together and creating stable orbits for electrons around the nucleus.
