Tell 2 uses of electroscope?
define earthing
When a positively charged body is brought near an uncharged metal rod, the part of the rod near the charged body acquires a negative charge, and the far side a positive charge. Can you say why this happens? Remember that in a body negative charge are mobile whereas positive charge are fixed.
