Gauss's Law


UNIT: Electrostatic Field

PURPOSE: Illustrate charging by induction and conduction.

EQUIPMENT:
1 Project-O-Scope
2 Silk Fabric
3 Glass Rod

SUGGESTIONS:
1 Predict whether positive or negative charges are left after you remove both your hand and the charged rod.
2 Conduct this experiment in a dry environment.
