Final answer:

When rubbing a Perspex rod with cloth, it becomes positively charged. This charge leads to an attraction between the rod and small pieces of paper due to the electrostatic force.

Explanation:

Charging the Perspex rod: Rubbing Perspex rod with cloth transfers electrons, leading to a net positive charge on the rod.

Explanation of charging: Charging occurs due to the transfer of electrons; the Perspex rod gains electrons from the cloth, resulting in a net positive charge on the rod.

Attracting small pieces of paper: The charged rod attracts small pieces of paper due to the electrostatic force between the positive charge on the rod and the negative charge on the paper.
