What is sure test of electrification attraction or repulsion Why?

Attraction may occur between two oppositely charged bodies or a charged body and an uncharged one. That is why in attraction, one is not sure if both bodies are charged, However in repulsion, there are two bodies that have the same charge. That is why repulsion is the sure test of electrification.

What is sure test of electrification attraction or repulsion?

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.

What is sure test of electrification?

Repulsion is the sure test of electrification. Note: If two bodies are electrified (i.e., charged they can either attract or repel). If they are: (a) attracted: this is not only possible by electrification but can also be due to the attraction of an uncharged body with charged body.

Which is better test of the charge on an object attraction or repulsion Why?

Repulsion is said to be the sure test to find whether an object is charged or not because attraction can occur between an uncharged body and a charged body due to induction of charges from the charged body to the uncharged body.

Why is repulsion sure tested?

We say that repulsion is a sure test of charge in body because we can test charge by only two way one is attraction and second is repulsion. … magnet attracts an non magnetic iron but an charged body can give repulsive force to only another charged body.

What is electrification explain?

Electrification is the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source. The broad meaning of the term, such as in the history of technology, economic history, and economic development, usually applies to a region or national economy.

Why do we say that only repulsion is a short test of charge on a body?

Because when we bring a charged body near an uncharged body an opposite charge is induced on the neutral body. And their will an attraction between them. Therefore, repulsion is a sure test of charge. …
