Question:
There is given an ideal capacitor. The capacitor consists of two plates at a distance of 1mm, in a Cartesian coordinate system the plates are parallel to the (x,y) plane.
The capacitor will be charged such that an electrical energy of 10~ J will be stored in the capacitor and then it will be
disconnected from the voltage source. You know that the stored energy W of a capacitor is given by W = -QU where Q is
the stored charge and U is the applied voltage.
Now you bring in a dielectric material with a relative dielectric constant of 3 which exactly fits between the two plates. You bring in the dielectric material by moving it without friction along the x-axis. The dielectric material has a mass of 10g.
What will be the velocity Up of the dielectric material just at that moment when it is completely between the two plates of the capacitor?
