5C20.2 Force on a Dielectric

[Setup Time: 25 Min.] [Current Condition: Not Working Well]

Info

A rider with a large dielectric attached above it is placed on an inclined air-track so that it is partially inserted between the parallel plates of a capacitor. When a high voltage is applied to the plates, the rider is pulled back up the track until the dielectric is entirely between the plates.
