Is it possible that there is only one type of charge?

4 Answers. No, there are only positive and negative charges. Or, more carefully stated, if there is a another type of charge, then electromagnetism is not what we are currently thinking it is.

What is charge equal to?

Charge thus exists in natural units equal to the charge of an electron or a proton, a fundamental physical constant. A direct and convincing measurement of an electron’s charge, as a natural unit of electric charge, was first made (1909) in the Millikan oil-drop experiment.

What is a magnitude charge?

The magnitude of the electric field is simply defined as the force per charge on the test charge. Since electric field is defined as a force per charge, its units would be force units divided by charge units. In this case, the standard metric units are Newton/Coulomb or N/C.

Is it possible for an object to have more than one type of charge?

If the same amounts of negative and positive charge are found in an object, there is no net charge and the object is electrically neutral. If there is more of one type of charge than the other on the object then the object is said to be electrically charged.

When you rub one material to another they are charged by?

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.

Is it possible for an object to have more than one type of charge at the same time?

Can an object be charged negatively with the help of a positively charged object?

Losing electrons results in more positive charge than negative charge, making the object charged positively. Gaining electrons results in more negative charge than positive charge, making the object charged negatively.

How do charge interact?

If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity. The two charges attract each other.

When two objects made of different materials are rubbed together they each acquire a charge?

When two different materials are rubbed together, there is a transfer of electrons from one material to the other material. This causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer).

Can a charge exist without mass?

If a charged body is put in contact with an uncharged body, uncharged body becomes charged due to transfer of electrons from one body to the other. i.e., charge can not exist without mass though mass can exist without charge.

What is the charge on objects A B and C?

Solution Objects A , B and C are three identical, isolated, spherical conductors. Originally A and B both have charges of +3 mC, while C has a charge of –6 mC. Objects A and C are allowed to touch, then they are moved apart. Then objects B and C are allowed to touch, and they are moved apart.

What is the smallest charge that can exist in nature?

When a physical quantity can have only discrete values rather than any value, the quantity is said to be quantised. The smallest charge that can exist in nature is the charge of an electron. Charge on a body can never be , or etc.

What happens to the mass when an object is negatively charged?

When an object is negatively charged it gains electrons and therefore its mass increases negligibly. Similarly, on charging a body with positive electricity its mass decreases. Change in mass of object is equal to n ´ me. Where, n is the number of electrons transferred and is the mass of electron .
