Question

A plastic rod becomes negatively charged when it is rubbed with a piece of wool. How does the rod become charged?

Electrons move from the rod to the wool.
Protons move from the rod to the wool.
Electrons move from the wool to the rod.
Protons move from the wool to the rod.

Answer 1

Electrons move from the wool to the rod.

BEcause if they move from wool to rod, the rod has more number of electrons now. Hence making it negatively charged

Answer 2

The plastic rod becomes charged when electrons move from the wool to the rod to become negatively charged. Details about charge can be found below.

What is electronegativity?

Electronegativity is the tendency, or a measure of the ability, of an atom or molecule to attract electrons and thus form bonds.

According to this question, a plastic rod becomes negatively charged when it is rubbed with a piece of wool.

An atom becomes negatively charged when it gains electrons from another atom, hence, it can be said that the plastic rod becomes charged when electrons move from the wool to the rod to become negatively charged.
