When we rub a glass rod with silk, some electrons are transferred from the rod to the silk. The rod becomes positively charged. The silk becomes negatively charged.
The coulomb is a very large amount of charge. A typical charge acquired by a rubbed body is 10 - 8 C. How many electrons have been added to or removed from it? Since the charge is positive, there is deficiency of electrons. The particles such as photon or neutrino have no rest mass. Hence, these particles can never have a charge. The mass of a body slightly increases when it acquires a negative charge by gaining some electrons.
On the other hand, when a body acquires a positive charge by losing some electrons , its mass slightly decreases. In other words, charge can neither be created nor destroyed.
It can be transferred from one body to the other.
Or, equal amounts of positive or negative charges can appear or disappear. This is what happens in pair production and pair annihilation, as shown in figure. In pair production energy is converted into mass, while in annihilation mass is converted into energy. Conservation of charge holds good in all types of reactions.
