Q16. A positively charged rod is placed near the brass cap of the electroscope. The gold leaf flips away from the brass plate because....
protons are repelled downwards from the brass cap causing both gold leaf and brass plate to be positively charged and repel each other.
electrons are attracted upwards towards the brass cap causing both gold leaf and brass plate to be positively charged and repel each other.
electrons are repelled downwards from the brass cap causing both gold leaf and brass plate to be negatively charged and repel each other
protons are attracted upwards to the brass cap causing both gold leaf and brass plate to be negatively charged and repel each other.
