Question

The following are steps in an investigation into electrically charged objects. Step #1: Blow up a balloon. Step #2: Rub the balloon against your hair. Step #3: Rub a plastic fork against your hair. Step #4: Bring the two objects together and observe what happens. Which steps are required to charge the objects? Steps #1 and #2 Steps #2 and #3 Steps #3 and #4 Steps #1 and #4

Answer 1

Steps #2 and #3 is the correct answer.

• The objects will be having static electricity. It is created by rubbing the objects.
• Static electricity is created as rubbing the objects causes imbalance of positive and negative charges. This is because rubbing transfers negative charge which builds up on the surface of object.
• There are three methods for creating static electricity, which are charging the object by induction, conduction and friction.
