Limit of charing a body by positive charge

Click For Summary
SUMMARY

The discussion centers on the limitations of positively charging a body, specifically addressing the scenario of charging in a vacuum versus air. It is established that a body can only be charged positively by removing electrons, and there exists a definitive limit to this process, which is reached when all electrons are detached. The participants also explore the concept of adding positively charged particles as an alternative method of charging, while questioning the implications of completely removing electrons from a body and whether it can lead to the creation of new electrons.

PREREQUISITES
  • Understanding of electric charge and electron behavior
  • Knowledge of dielectric strength of air and vacuum
  • Familiarity with concepts of positive ions and particle physics
  • Basic principles of electrostatics
NEXT STEPS
  • Research the dielectric strength of air and its implications for charging bodies
  • Explore the behavior of charged particles in vacuum environments
  • Study the principles of ionization and electron detachment
  • Investigate the role of positive ions in maintaining structural integrity of charged bodies
USEFUL FOR

Physicists, electrical engineers, and students studying electrostatics and particle physics will benefit from this discussion, particularly those interested in the limits of electric charge and the behavior of electrons in different environments.

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 positive 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
