Question

An electroscope is a device that detects charge on objects that touch it or are brought near it. John rubs a piece of cotton fabric on a plastic rod and then touches the rod to the electroscope. What methods of charging does John use? John charges the rod through induction, then charges the electroscope through friction. John charges the rod through conduction, then charges the electroscope through induction. John charges the rod through friction, then charges the electroscope through induction. John charges the rod through friction, then charges the electroscope through conduction.

Answer 1

The answer is D 2021 edge

Step-by-step explanation:

Answer 2

John charges the rod through friction, then charges the electroscope through conduction.

Step-by-step explanation:

When John rubs a piece of cotton fabric on a plastic rod , charge is produced when dislocation of some electron takes place through the process of friction .

When he touches the rod to the electroscope, charge is transferred to electroscope through the process of conduction . Induction involves transfer of charge without touching . In this case charge transfer takes place through conduction .
