Electrostatics
A parallel plate capacitor filled with empty space has a capacitance C, it is charged to a potential difference Vo and then disconnected from charing source. then a slab of dielectric constant K, essentially as thick as the plate spacing is inserted part way between the plates. As a function of x, the distance of insertion, what is (a) Vx, the voltage across the plates (b) the energy stored in the field of the capacitor?. An instructor when demonstating this lost hold on the dielectric when it was halfway in (x=l/2). If the slab had a mass m and the plates were smooth, how fast was the slab moving when it completely filled the capacitor?
