Haley rubs a cotton cloth along a plastic strip. The plastic strip becomes positively charged. Why did this happen? A. The plastic strip gained protons from the cotton. B. The plastic strip lost protons to the cotton. C. The plastic strip gained electrons from the cotton. D. The plastic strip lost electrons to the cotton.

The answer would be D, when the plastic strip and cloth are rubbed together there is a transfer of electrons from the plastic strip to the cloth leaving the plastic strip positively charged as it lost electrons, while the cloth becomes negatively charged.

The plastic strip becomes positively charged because it has lost some electrons that are gained by the cotton. Hence, option (D) is correct.

What is Static Electricity?

The phenomenon by which a surface accumulates some extra amount of electric charge due to the rubbing of one surface over the other is known as static electricity.

In the given case,

When the cotton cloth is rubbed against the plastic strip, then the plastic strip losses some electrons. Since electrons are the negatively charged entity, therefore due to electron loss, it acquires a net positive charge on its surface.

While the electrons lost by the plastic strip are gained by the cotton, hence it acquires some negative charge on its surface. The positive charge on the surface of the plastic strip is due to the presence of more protons than electrons.

Thus, we can conclude that the plastic strip becomes positively charged because it has lost some electrons that are gained by the cotton. Hence, option (D) is correct.
