Bring a negatively 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. This show that unlike charges attract each other.
Beside above, do similar charges attract?
According to this classical law, particles with like charges repel and those with unlike charges attract.
Hereof, what are 3 ways to put a charge on an object?
In order to charge an object, one has to alter the charge balance of positive and negative charges. There are three ways to do it: friction, conduction and induction.
What are like charges examples?
(i) If a glass rod is rubbed with a silk cloth, it acquires a positive charge while the silk cloth acquires an equal amount of negative charge. (ii) If an ebonite rod is rubbed with fur, it becomes negatively charged, while the fur acquires equal amount of positive charge.
What are the unlike charges?
There are two types of charges, positive and negative. Same type of charges (two positive or two negative) repel each other, while unlike charges (one positive and one negative) attract each other.
What are unlike charges and like charges?
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. The size of the force varies inversely as the square of the distance between the two charges.
What do like charges do?
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. This repulsive force will push the two objects apart.
What is always between like charges?
Like charges always attract each other and unlike charges always repel each other.
What is gold leaf electroscope?
A gold-leaf type electroscope is a device used to detect the presence of electric charge on a body and its relative amount. The electroscope is usually constructed with a metal plate or sphere at the top of a metal post (electrode) with thin foil leaves (e.g., gold) hanging from the bottom of the post.
Why do like charges repel and unlike attract?
But here, it is the excess number of electrons, which causes repulsion among the two negative charges. Thus, using quantum mechanics, electrostatic attraction and repulsion are explained with the help of transfer of virtual photons. Therefore, like charges repel and unlike charges attract.
Why do two like charges repel?
If two positive charges interact, their forces are directed against each other. This creates a repellent force as shown in the illustration. (The same occurs with two negative charges, because their respective forces also act in opposite directions.)
