What is the sure test of charging?

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.

What is the 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.

How do you find the presence of a charge?

The electroscope is an early scientific instrument used to detect the presence of electric charge on a body. It detects charge by the movement of a test object due to the Coulomb electrostatic force on it. The amount of charge on an object is proportional to its voltage.

Which charges attract and which charges repel?

Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.

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.

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 …

Which electric component or device is used to detect presence of charge in circuit?

electroscope
An electroscope is a device that detects static electricity by using thin metal or plastic leaves, which separate when charged.

How do you prove like charges repel each other?

Experiment: Take a glass rod rubbed with silk piece (+vely charged) Suspend it in a stand with the help of a thread. Bring a -vely charged Ebonite rod (rubbed with fur) near the glass rod. Attraction is seen between the two rods. Now interchange them i.e. suspend B and bring A near it, again attraction is there.
