• This question comes from the study of electrostatics.
Materials that can be charged from the options are; plastic and glass.
• Now, among the 3 listed materials, plastic and glass are insulators whereas metal is a conductor because it can conduct electricity.
• With respect to insulators and conductors as regards charging by electrostatics, we can say that in conductors if you charge a portion of them, the charges inside will have the freedom of movement. However, inside of the material, If a charge is added in another portion of the conductor, the previously introduced charges will combine to neutralize this new charge.
• With respect to insulators, the charges that are put at the surface of the object will remain there because unlike conductors, these insulators do not allow for freedom of movement of charges inside the material that could neutralize.
• Thus, the materials that can be charged by rubbing are plastic and glass.
