| - | 1. Move the balls so that they are just touching. One terminal of electrostatic generator to the balls and the other to the grounded frame. The balls should repel about 5 cm. The frame is set up in front of the horizontal projector. 2. Separate balls and connect them to the +ve and -ve of the generator and observe attractive force. 3. Can repeat attractive force experiment at different separations to show that force increases as separation decreases. A larger version of this demo (shown below) is available for use in Hebb theater. Can also demonstrate with two balloons charged with cat fur. Updated on 06/10/13 | + | 1. Move the balls so that they are just touching. Attach one terminal of Wimshurst Generator to the balls. The balls should repel about 5 cm. The frame is set up in front of the horizontal projector, or on camera. |
