Question

Statement 1: Plastic rod becomes negatively charged when rubbed with a cloth.
Statement 1: Glass rod becomes positively charged when rubbed with a cloth.
Explain both the statements.

Answer 1

When a plastic rod is rubbed with a cloth, the plastic rod becomes negatively charged as electrons from the cloth are deposited on the plastic rod.

The plastic rod becomes negatively charged because the plastic possesses a more significant attraction for electrons than the cloth.

The glass rod becomes positively charged because the cloth possesses a more significant attraction for electrons than the glass rod.
