Final answer:
An electron near another electron experiences repulsion, which is explained by the electromagnetic force that dictates like charges repel each other.
Step-by-step explanation:
An electron situated near another electron would feel repulsion due to the electromagnetic force. In physics, we learn that like charges repel each other. This is one of the four fundamental forces and is responsible for the behavior of electrically charged objects. It is also the force that holds the atom together by attracting negatively charged electrons to the positively charged nucleus, despite the repulsion between the electrons themselves.
Nonetheless, the strong nuclear force mainly acts to hold protons and neutrons together in the nucleus and does not influence the electrons directly. On the other hand, gravity, the weakest of the four fundamental forces, has a negligible impact on the behavior of subatomic particles like electrons within atoms.
