Attraction may occur between two oppositely charged bodies or between a charged body and an uncharged one. That is why, in attraction, one is not sure whether 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.
Why attraction is not a sure test for electrification?
This is because repulsion is observed only when two bodies have like charges and this means that the bodies must be charged. … 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.
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).
Why repulsion is sure test of charge of an object?
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.
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 can we ignore quantization of charge when dealing with macroscopic charges?
In macroscopic or large scale charges, the charges used are huge as compared to the magnitude of electric charge. Hence, quantization of electric charge is of no use on macroscopic scale.
Why do we ignore Quantisation of charge at macroscopic level?
This means that macroscopic charges are very huge as compared to the magnitude of an electric charge. … This is the reason when we are dealing with charges at macroscopic level, the quantization of charge is ignored and it is considered that the electric charge is continuous.
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.
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.
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.
