What happens when a perspex rod is held near a polythene rod?

When a perspex rod is held near a polythene rod, the two rods will interact due to static electricity. If the perspex rod is positively charged (after being rubbed with a cloth), it will attract the negatively charged polythene rod, which has gained electrons. This attraction occurs because opposite charges attract, resulting in an electrostatic force between the two rods. If both rods are similarly charged, they will repel each other.
