4.1 ELECTRICITY

P41 006

The diagram shows a positively charged perspex rod and a negatively charged electroscope when they are far apart.

The positively charged rod is slowly moved closer to the negatively charged electroscope. As this motion takes place, the leaves of the electroscope are observed to first collapse and then diverge. Explain the observations using a series of diagrams showing the charge distribution on the electroscope.
