Electrons & Earthing: Effects on Neutralization & Earthed Objects

[SleSSi]

If protons are neutralized with the electrons, then a group of electrons come close and repel them,if the opposite side of the object is earthed, will they get earthed or just move away somewere in that object? and if the object was large enough would they stop half-way after they stop feeling the repulsion or go as far away as possible anyway?

Nature tends toward charge neutrality. As far as we know, for every positive charge, there is a negative charge.

The nuclei of atoms contains protons (and neutrons). Surrounding the nuclei are electrons, each with equal but opposite charge.

If there is a group of electrons, they tend to be distributed in a manner of the least energy state. At some point, the excess charge of electrons will cause a discharge, e.g. lightning.

If one charges a conductor, the charge will 'leak' and at some point, when a critical charge density has accumulated, a discharge will occur.

A group of electrons would not 'stop half-way' but each electron will be attracted to a positive charge (+ ion) somewhere.

When electrons are added to an object, they can neutralize any excess protons and bring the overall charge of the object to neutral. However, if there are still more electrons present, they can create a repulsive force that causes them to spread out and move away from each other.

If the opposite side of the object is earthed, it means that it is connected to the Earth, which acts as a large reservoir of electrons. In this case, the excess electrons will flow through the earthed connection and be neutralized, as the Earth can absorb and dissipate an infinite amount of electrons.

As for the question of whether the electrons will just move away somewhere in the object or stop halfway, it depends on the size and shape of the object. If the object is small and compact, the electrons may just redistribute themselves evenly throughout the object. However, if the object is large enough, the electrons may continue to move towards the earthed end until they reach a point of equilibrium where the repulsive force is balanced by the attractive force of the earthed connection.

In any case, the end result is that the excess electrons will be neutralized and the object will have a balanced charge. This is why earthing is important in electrical systems, as it helps to prevent the buildup of excess charge and potential hazards.
