WHO found that like charges repel?
Benjamin Franklin
Can two like charges attract?
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. …
Can a positively charged body can attract another positively charged body?
yes, they can attract each other when one of them is very very large than the other. then, the electrostatic force acting on the two is not due to their initial charges but will be due to the charges produced due to induction and hence attraction takes place.
Can a positively charged body attract a positively charged body?
A positively charged body can attract another positively charged body.
What happens when a negatively charged body touches a neutral body?
During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively.
When a body is negatively charged by friction it means?
When a solid body is negatively charged by friction, it means that the body has acquired excess of electrons. If the body loses electrons it becomes positively charged and if the body gains electrons it becomes negatively charged . Was this answer helpful?
What happens when a body is charged by friction?
The triboelectic charging process (a.k.a., charging by friction) results in a transfer of electrons between the two objects that are rubbed together. As a result, the atoms of rubber pull electrons from the atoms of animal fur, leaving both objects with an imbalance of charge.
How is friction charged by the body?
When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be ‘rubbed off’ one material and on to the other. The material that gains electrons becomes negatively charged.
Can be negatively charged by?
A body can be negatively charged by adding some excess electron to it.
What is the minimum charge on an object?
The minimum net charge that an object can get is one electron’s charge, which is 1. 6×10−19 coulomb.
When a body can be charged negatively then?
Hence, A body can be negatively charged by Giving excess of electrons to it.
What happens to the mass of the body when it is 1 positively charged 2 negatively charged?
Answer. Answer: Since we know that charging of a body depends upon transfer of electrons. So, if a body becomes negatively charged it will gain electrons that is its mass will increase and if a body becomes positively charged it loses electrons hence its mass will decrease.
Who discovered positive and negative charges?
How can an object be charged by contact?
Charging by conduction involves the contact of a charged object to a neutral object. In contrast to induction, where the charged object is brought near but never contacted to the object being charged, conduction charging involves making the physical connection of the charged object to the neutral object.
How do we determine a charged object?
The quantity of charge on an object reflects the amount of imbalance between electrons and protons on that object. Thus, to determine the total charge of a positively charged object (an object with an excess of protons), one must subtract the total number of electrons from the total number of protons.
