Question

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

a.electrons move from the rod to the wool.
b.protons move from the rod to the wool.
c.electrons move from the wool to the rod.
d.protons move from the wool to the rod.

Answer 1

electrons move from the wool to the rod

Answer 2

Answer;

c.electrons move from the wool to the rod.

Step-by-step 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.
