Question

A glass object receives a positive charge of +3 nC by rubbing it with a silk cloth. In the rubbing process have protons been added to the object or have electrons been removed from it?

Answer 1

Answer: A glass object receives a positive charge of +3 nC by rubbing it with a silk cloth. In the rubbing process electrons been removed from it.

Explanation:

It is known that for every atom the protons and neutrons reside in the nucleus of the atom. Whereas electrons move outside the nucleus of an atom. As a result, electrons are able to transfer more easily from one substance to another as compared to the protons.

This is because protons are tightly held by the nucleus of an atom. Whereas electrons are mobile in nature and hence, they can easily move.

Therefore, positive charge on the glass develops due to the removal of electrons from it.

thus, we can conclude that in the given process electrons been removed from the glass object.
