What happen when some one touch the discs of negatively charged electroscope
Answers
Answer:
The charge becomes grounded. Means, it simply goes to the ground and becomes neutralised.
Explaination:
Why does this happens ?
Our earth is the ocean ocean of electrons. The negative charges are always in search of a positive charge ,as it gets attracted to it. On touching a disc , the negative charges flows through the body of a person to reach a positive. And it goes into ground.
Why it easily flows through human body?
Because of the fact that human body is a good conductor.
What is the scientific name of this phenomenon?
It's called earthing.
Interesting fact :
This earthing is somehow used to protect tall buildings through electric shocks. An arrangement is made as such that as electrode is place under ground level connecting the non-current carrying part of the system. The wire which has equipped in the system has a very low resistivity. The electrical charge flowing through these get's grounded and this is how earthing helps us by protecting from severe , deadly electric shocks.
