Question
The strips of an electroscope diverge when a charged body is brought in contact with the metal clip. Now the clip is touched gently by our hand. What will happen to the strips? Explain.

Solution
If we touch the strip standing on the ground (not on any insulating base), then the charge on the strip will pass through our hand to the ground and the strips will contract.

In an electroscope, if a negatively charged body is brought in contact with the metal dip, the strips of the electroscope diverge. If now another charged object carrying equal amount of positive charge is brought in contact with the clip, what will happen?
If the metal clip used in the electroscope is replaced by an ebonite rod and a charged body is brought in contact with it, will there be any effect on the aluminium strips? Explain.
Assertion: Insulators do not allow a flow of current through them.
Reason: Insulators have no free charge carrier
Assertion: When both the strips of the electroscope are charged with a similar charge, they repel each other and become wide open.
Reason: Like charges always repel each other.
Assertion: People struck by lightning receive a severe electrical shock.
