Which one is the better way to test a body charged or uncharged attraction or repulsion explain?

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

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 only repulsion is a sure test of charge on a body?

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 the attraction or repulsion between electric charges?

The attraction or repulsion between charged particles is called electric force. The strength of electric force depends on the amount of electric charge on the particles and the distance between them. Larger charges or shorter distances result in greater force.

Which effect proves more conclusively that an object is charged?

Repulsion can prove conclusively that the object is charged.

Which is the sure test of charge on a body?

Repulsion is being considered as the sure test of charge on body as the induction of charge is possible between an uncharged body and charged body when brought close together.

Why attraction is not the true test of electrification?

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.

Why is repulsion a surer test for magnetism?

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 …

Which test is not the surest test to know the presence of charge on a body?

Attraction is not a sure test to detect presence of charge on a body.

Is Silk positively or negatively charged?

Since the glass and silk have opposite charges, they attract one another like clothes that have rubbed together in a dryer. … A glass rod becomes positively charged when rubbed with silk, while the silk becomes negatively charged. (a) The glass rod is attracted to the silk because their charges are opposite.

What do two uncharged objects do?

When two neutral objects come into contact–especially in a dry environment–electrons can be knocked loose from one object and picked up by the other. The object that gains electrons becomes negatively charged, while the object that loses electrons becomes positively charged.

Do positive and negative charges repel?

Like charges repel each other (positive to positive or negative to negative). Most of the time positive and negative charges are balanced in an object, which makes that object neutral. Static electricity is the result of an imbalance between negative and positive charges in an object.

Do opposite charges attract?

If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity. The two charges attract each other.

Can a positively charged body attract another positively charged body?

Yes… two positively charged bodies can attract each other under the phenomenon of electrostatic induction. … They are much stronger than even electrostatic forces or coulombian forces.

How do charged bodies interact with other bodies?

In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. … Objects with like charge repel each other.

What happens when two charged bodies are touched?

When two identical bodies having different magnitude of charge are touched, the redistribution of charge takes place and both the bodies acquire same charge.
