there are three way of the subjects can be given a net charge.there are charging by friction.this is useful charging insulators .if you rub on material with another electrons have a tendency to be transferred from one material to the other .

"The charge on the materials can be determined by the application of the Coulomb’s Law.
If a charge q exerts a force on another charge Q, by Coulomb's law the equation is given as follows:
Coulomb’s Law F= kqQ/r2, where K is the constant which is equal to 8.99 * 10 to the power 9 Nm2/C2 and r stands for the distance between the two charges.
There are two charges, positive charge and negative charge.
Like charges repel each other whereas unlike charges attract each other.
