Question

Is repulsion a true test of electrification?

Answer 1

Hint: This question is based on the concept of repulsion. Repulsion can be defined as a force tending to separate two objects, such as the force between two like electric charges or magnetic poles. Repulsion takes place between similar or like objects.

Complete answer:
The two basic forces which act in electrostatics are attraction and repulsion. Attraction is defined as a force which tends to draw two bodies together. Attraction takes place between two oppositely charged particles. The best example of attraction is a charged comb, which will attract small objects such as grains of sugar when brought close to them.
Repulsion can be defined as a force tending to separate two objects, such as the force between two like electric charges or magnetic poles. The example of repulsion is that two electrons tend to move away from each other as they both have negative charge.
Repulsion is considered as the true test of electrification. This is because repulsion is observed only when two bodies have like charges and this means that the bodies must be charged. Hence, repulsion is a true test of electrification.
On the other hand, attraction cannot be considered as a true test of electrification as attraction can also take place between a charged particle and a neutral particle. Hence, only repulsion is a true test of electrification.

Note:
Electrification is defined as the process that produces electric charges on an object. There are many different actions that can produce an electric charge. When this charge is produced on an object it is called an electrostatic charge. An electrostatic charge is a charge confined to an object and the charge is in a static position.
