Question

when you rub a glass rod with silk, the rod becomes positively charged and the silk becomes negatively charged. as a consequence, a. the rod and silk both gain a tiny amount of mass

Answer 1

When you rub a glass rod with silk, the rod becomes positively charged and the silk becomes negatively charged. This transfer of charge does not change the mass of either material.

Step-by-step explanation:

When you rub a glass rod with silk, the rod becomes positively charged and the silk becomes negatively charged. This happens because when the two materials come into contact and then separate, electrons are transferred from the glass rod to the silk. The glass rod loses electrons and becomes positively charged, while the silk gains electrons and becomes negatively charged.

It's important to note that this transfer of charge does not result in a change in mass for either the glass rod or the silk. The mass of an object is determined by its number of protons and neutrons, which remain constant during this process of charging.
