Final answer:
The phenomenon wherein two similarly charged objects repel each other is known as electrostatic repulsion. This is a result of the law of physics stating that like charges repel, while unlike charges attract.
Step-by-step explanation:
When two rods carrying similar charges push each other away, this phenomenon is known as electrostatic repulsion. According to the laws of physics, particularly Coulomb's law, like charges repel, while unlike charges attract. This principle is universally applicable. For instance, in the case of two negatively or positively charged rods, they will repel each other due to the electrostatic forces between them.
