Limit of charing a body by positive charge

In summary: I was just thinking that if you have detached all the electrons from a body, than the body would essentially become a vacuum. This would mean that there would be no electrons in it, and it would be unable to hold any more.

Hello all,


I always read in texts that you can charge a body in air till the the electric field due to body does not exceeds the dielectric strength of air, which has a certain value. The question that is popping into my head is that, what if we charge the body in vacuum? I expect that even in vacuum one can not charge(positively) a body indefinitely . A body can be charged positively by detaching electrons from it, but as such a given mass of body has a definite number of electrons, this let me feel that there is a limit of charging a body by positive charge and this limit is reached when the body lose all of its electrons. Please clarify this as it is just my thinking there may be something beyond my understanding.
Thanks a bunch

There are other ways to charge a body. You can always add a positively charged particle to it.

Thanks s.g. but this not my concern. I know by adding positive charged particles there can accumulation of desired number of postive charge, what I want to know is the situation when we have detached all electrons (free or bound if possibility exist) from a body than will our system( which definitely consists of lot of positive charge) re-create somehow more electrons or in other words the possibility of "zero charge" of any type(+ve or -ve) never exist and this always let us draw more and more electrons from the body irrespective of the number of electrons it carries during normal neutral state? Is that could be the case?

Way before you remove all the electrons, the body will not be a body anymore.
What keeps the positive ions together in a solid body?

Ok Guys thanks
 

FAQ: Limit of charing a body by positive charge

What is the limit of charging a body by positive charge?

The limit of charging a body by positive charge depends on several factors such as the size and shape of the body, the material it is made of, and the amount of charge being applied. However, in general, the limit is when the repulsive force between the charged particles becomes greater than the attractive force between the charged particles and the body.

Can a body be charged indefinitely with positive charge?

No, a body cannot be charged indefinitely with positive charge. Eventually, the repulsive force between the charged particles will become too great and the body will reach its limit of charging.

What happens when a body reaches its limit of charging by positive charge?

When a body reaches its limit of charging by positive charge, it will no longer be able to hold any additional charge. Any additional positive charge applied to the body will repel the existing charged particles and will not be able to stay on the surface of the body.

Is there a way to increase the limit of charging a body by positive charge?

Yes, the limit of charging a body by positive charge can be increased by changing the material of the body. Some materials, such as metals, have a higher limit of charging compared to others.

What are some real-world applications of the limit of charging a body by positive charge?

The limit of charging a body by positive charge is an important concept in the field of electrostatics and has many practical applications. It is used in designing electrical systems, controlling static electricity, and in the production of electronic devices. It is also important in understanding the behavior of lightning and other natural phenomena.
