Explain why a charge body loses its charge if we touch it with our hand?

When we touch a charged body with our hand, the charge is transferred from the charged body to our hand. This happens due to the process of conduction, where charges flow from a region of higher charge density to a region of lower charge density.

Our body is made up of atoms, which consist of positively charged protons in the nucleus and negatively charged electrons orbiting around the nucleus. When we touch a charged body, the excess charge on the body repels the electrons in our hand, causing them to move away from the region of higher charge density (charged body) to the region of lower charge density (our hand).

As a result, the excess charge on the charged body is neutralized by the transfer of electrons to our hand. This equalizes the charge distribution between the charged body and our hand, causing the charged body to lose its charge.

In summary, when we touch a charged body with our hand, the excess charge on the body is transferred to our hand through conduction, leading to the neutralization of the charged body and the loss of its charge.
