Rod is stillnegative

Once contact is made, electrons are transferred from the charged rod to the knob of the electro-scope. Charging by contact is called conduction.

Negatively Charged Electroscope Was the rod usedpositively charged ornegatively charged?

The rod used was negatively charged.

What is the final charge onthe electroscope when chargedby conduction with a negativelycharged rod?

The final charge on the electroscopewhen charged by conduction witha negatively charged rod is negative.

Make a note of this!
