Which of the following occurs when charging by rubbing? a. electrons are created through friction. b. protons combine with neutrons, leaving a net negative charge. c. electrons are ripped off one material and held tightly by the other material. d. protons are ripped off one atom and congregate on another.

The correct answer to the question is- C).Electrons are ripped off one material and held tightly by the other material.

EXPLANATION:

Before going to answer this question, first we have to understand the charging by friction.

There are three modes of charging a body, which are known as friction,conduction, and induction.

Friction: Friction is the type of charging a body due to the actual transfer of electrons when two substances of different electron affinities are rubbed with each other. During rubbing, the electrons from less electron affinity substance will be transferred to high affinity substance.

The substance which will accept electrons gets negatively charged, and the other substance will be positively charged.

There will be no transfer of protons from one substance to another as protons are bound inside the nuclei of atoms.

Hence, the correct answer to the question is that electrons are ripped off one material and held tightly by the other material.
