Insulators can be charged by which of the following process?

Step-by-step solution

Charging by friction involves the transfer of electrons between two neutral insulating materials when they are rubbed against each other. This process results in one material gaining electrons and becoming negatively charged, while the other loses electrons and becomes positively charged. Induction is a process typically used for conductors, where charge is redistributed without physical contact. Heating does not inherently create a net charge on an insulator. Diverging is not a standard method for charging materia
