Electroscopes and Ebonite Rods?
I have an electroscope, an ebonite rod and a plastic ruler. I rub both of them on fur, and bring them near the the sphere of an electroscope without touching it. Both of them near it make the leaves of the electroscope flare outwards. What charge is on both of the rods (negative?) and what charge is on the electroscope?
If a charged object is brought near the electroscope terminal, without touching it, the leaves also diverge, because charges in the disk with identical polarity to the charged object are repelled to the leaves. If the electroscope is touched, and hence grounded, in this condition, the leaves close, but spread again if the charged object is moved away. The electroscope becomes charged with polarity opposite to the polarity of the charge in the object. The electroscope was charged by electrostatic induction.
I think you are right both will charge negative, the leaves will also be negative, since the top of electroscope will be positive, and charge separation means leaves are -ve. When the electroscope is grounded with charged object still close, then isolated again. the leaves will still repel but this time positive.
Hope clear and helps!
