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

why repulsion is the sure test to find whether a object is charged or not. 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.

Which is the most accurate 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. But the given body is uncharged. Therefore, repulsion is a sure test of charge.

Why attraction is not a sure test for charge?

Complete answer:

Attraction takes place between two oppositely charged particles. … 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.

Which is the true test of electrification attraction or repulsion?

Repulsion will only take place between two bodies if both the bodies are similarly charged. Hence repulsion is the surest test of electrification as it ensures that both of the bodies are charged.

Why repulsion is a sure test?

Repulsion is the sure test for magnetism because it occurs only when two like poles of a magnet exist while the attraction phenomenon can occur between two unlike poles of a magnet and also between a magnet and a magnetic material means if there are two magnets they will attract each other and suppose if one material …

What is true test of charging?

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. But repulsion can take place only between two charged bodies.

Which instrument is used to detect charge on a body?

Electroscope is a scientific instrument that is used for detecting an electric charge and its polarity.

Can two bodies of same charge can attract each other?

Answer Expert Verified

yes, they can attract each other when one of them is very very large than the other. then, the electrostatic force acting on the two is not due to their initial charges but will be due to the charges produced due to induction and hence attraction takes place.

What do you mean by charging by conduction what kind of charge does the body acquire?

Conduction is the process of charging a body by touching it to a charged body. In this process, the body that is being charged acquires the same kind of charge as the charging body.

Which of the following charge on an object is not possible?

As per quantization of charge: Electric charge can exist only as an integral multiple of charge on an electron (-e) i.e. q = ± ne, where n is an integer. The Possible values of electric charge are q = ± 1e; ± 2e; ± 3e… Charge less than the charge on an electron (i.e. e = 1.6 * 10-19 C) is not possible.

Why do we say that repulsion is a short test of charge on an object?

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. …

What does an electric charge in uniform motion produces?

Hence, when an electric charge is in uniform motion, it produces an electric field that is also changing in position and travelling through space. Thus, this changing electric field produces a changing magnetic field. … Hence, the electric charge in uniform motion produces both electric and magnetic fields.

What is the process of charging an object without touching it?

Induction charging is a method used to charge an object without actually touching the object to any other charged object. An understanding of charging by induction requires an understanding of the nature of a conductor and an understanding of the polarization process.

Which of the two attraction or repulsion is a sure test of magnetism?

Therefore, with the attraction of two materials we cannot determine whether both of them act as magnets or show magnetism. Whereas, repulsion only occurs between the like poles of two magnetic substances. Therefore, repulsion is the sure test for magnetism.

Which is the most reliable test for magnetism?

In case of magnets, repulsion occurs only between like poles. Therefore, repulsion is the most reliable test for magnetism.

Why is it said that repulsion is a sure test of magnetism How would you distinguish between a magnet and a bar of a magnetic material by using this test?

A: Repulsion is a sure test of magnetism. B: Magnetic induction precedes attraction.
