Question: 1 / 400

How does charging by friction occur?

By connecting two objects electrically

Through the generation of electric fields

The transfer of electrons between two neutral objects that come into contact

When two neutral objects come into contact, the movement of electrons from one object to the other can occur, resulting in one object becoming positively charged and the other negatively charged. This is known as charging by friction. Option A is incorrect because it describes electrical current and connection, which is not related to the process of charging by friction. Option B is incorrect because it describes the generation of electric fields, which is a result of charged objects, not the process of charging itself. Option D is incorrect because it describes inducing a charge without physical contact, which is not a part of the process of charging by friction.
