Question

What do you observe in the leaves of the electroscope, when you touch a charged balloon with your hand before bringing it close to the disc of the electroscope?

Answer 1

Required observations:

Since you have touched the charged balloon with your hand before bringing it close to check the charge, the charges from the balloon either pulls/pushes electrons to the earth, and it is neutralises.

In short, the balloon is earthed now. Since our hands are in contact with the earth directly or indirectly$.$

Change in electroscope:

The discs will not show any change since the balloon is neutralised now. The discs deflect when there is some charge in a body kept close for charge checking.

Answer 2

Answer:

Required Answer :-

I observed that my hand is earthed. In which the charges go to earth and object losses the charge.

It involves change in process of charging.
