Answer: attraction is used as a test for identifying and electrically chargedobject.
Is only attraction a way of testing for charge?
Answer: Attraction is not a sure test for charge as a magnet can attract another magnet, but it can also attract a magnetic material(magnetic materials do not have a charge but are attracted towards magnets).
What is the true test of a 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.
Which is the most accurate test of charge on a body?
An electroscope is used to detect that a body is charged or not. It works on the principle that like charges repel while unlike charges attract each other. When the metal strips repel each other proves that the body is charged because repulsion is the sure test to detect that a body is charged or not.
Why do we say that only repulsion is a sure test of charge on?
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. as we know that an charged body attracts non charged body also.
Why is attraction not a foolproof way of testing for charge?
Also, two objects with unlike charges attract each other. So, if two nonmagnetic objects attract each other, you cannot determine whether both are charged or only one of them is charged. … In other words, attraction is not a foolproof way of testing for charge.
Which of the following can be charged by rubbing?
Explanation: Ebonite gets charged by rubbing on fur. Plastic also gets charged on rubbing by fur. and Amber also gets charged by rubbing on fur.
What is not true for electric charge?
Answer: D is not true charge of one electron is not one coloumb. Coulomb is very big unit of charge.
Which of the following charge 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.
Which of the following is true for electrical force?
Answer: b. electric forces is produced due to electrical charge.
What is the method to get a charged body?
There are three methods to charge a body, namely, charging by friction, conduction and induction. Charging a body by friction: When two uncharged or neutral objects made of different materials, say a glass rod and a silk cloth, are rubbed against each other, both objects get electrified due to a transfer of charges.
Can two bodies of same charge can attract each other?
Can two similarly charged bodies attract each other? Solution: Solution: Yes, when the charge on one body (q1) is much greater than that on the other (q2) and they are close enough to each other so that force of attraction between q1 and induced charge on the other exceeds the force of repulsion between q1andq2.
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.
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.
How many types of charges are gained by rubbing objects?
Explanation: There are two types of charges are gained by rubbing objects. They are positive and negative charge.
