Question

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

Answer 1

Answer;

c.electrons move from the wool to the rod.

Explanation;

-Atoms are generally neutral (have the same number of protons as electrons). Substances lose electrons to become positively charged, while other substances gain electrons to become negatively charged.

-When a plastic rod is rubbed with woolen cloth or wool, a transfer of electrons occurs (from the wool to the rod). The rod gains electrons; thus, it is negatively charged.

Answer 2

Electrons move from the wool to the rod
