Explanation:

A pith ball electroscope consists of a small pith ball suspended by a dry silk thread from an insulating stand.

To test the charge in a body, the body is brought near the pith ball without touching. If the pith ball moves towards the body, the body is charged and if the ball does not move, the body is uncharged.
