What does the pith ball experiment demonstrate ? |
|
Answer» tion:A pith ball is a very small, LIGHTWEIGHT object that picks up electric CHARGE quite well. A charged pith ball works well to show the Coulomb force between two charged OBJECTS. If a glass ROD is rubbed with SILK, the silk rubs some electrons off the rod. The rod thus becomes positively charged. |
