The knob of the electroscope lost electrons. Rubber rod The knob of the electroscope lost electrons. Therefore the knob is now net positive and the leaves are net negative The leaves repel each other and spread apart F es The leaves gained the electrons.

What would happen if the rod is taken away? Rubber rod The electroscope hasn’t lost or gained electrons so it is still neutral. What would happen if the rod is taken away? What would happen if the rod is taken away?

Rubber rod The electroscope hasn’t lost or gained electrons so it is still neutral. The electrons in the rubber rod are attracted to the NET POSITIVE knob of the electroscope.
