Describe Observation of a simple electroscope? What is the first statement of this audio clip?
The aluminium foil strips receive the same charge from the charged refill through the paper clip.
The strips carrying similar charges repel each other and they become wide open.
Touch the end of the paper clip gently with hand and you will find a change in the foil strips.
They come back to their original state.
The reason is that the foil strips lose charge to the earth through your body.
