5A20.15 Electric Force Between Plates

A device is availble to demonstrate the force between charged objects. One metal plate is connected to ground. Another plate connected to a spring is suspended several centimeters above grounded plate. This plate is connected to sphere of Van de Graaff. The plates will acquire opposite charges. The one on spring will move down until it touches other plate and charge is neutalized. The spring will then pull the plates apart.
