Question

A polythene rod may be charged by rubbing it with a cloth while being held in the hand but a metal rod cannot be charged in a similar way. Explain why

Answer 1

Step-by-step explanation:

This is because polythene rod is an insulator , therefore when it is rubbed with a cloth , electrons move easily therefore making it charged but

Metal rod is a conductor, it conduct heat . Therefore, their atoms have electrons that is constantly in motion. Therefore rubbing it with a cloth will make any difference in making it charged because it have very huge number of stable electrons which will not allow more electrons to move through them.
