Force on dielectric on pulling it out from capacitor
Well, let''s try and recreate the equation. We know that the standard, or at least, most accessible way to obtain the force on a dielectric as it is being inserted into/removed from a capacitor is to write the internal energy of the system as a function of how far, x, the dielectric has moved. We now usually have a choice on whether to write the energy as $frac{1}{2}CV^2$ …

Electric field intensity in a dielectric inside a capacitor
Thus electric field outside of dielectric in lower part of capacitor is not equal to the electric field in upper part of capacitor.

Fundamentals | Capacitor Guide
This effect of a capacitor is known as capacitance. Whilst some capacitance may exists between any two electrical conductors in a circuit, capacitors are components designed to add capacitance to a circuit. The capacitor was originally known as a condenser or condensator but is not widely used nowadays. Capacitance of a Capacitor

capacitance
If you then put equal amounts of energy into both capacitors, you will find that the one with the solid dielectric does have a lower voltage, due to the properties of the dielectric, but this is not the same as having lower energy density. This is because higher energy density means more joules in the capacitor per volt on it, so it takes less voltage to store the same …

Oscillations of Dielectric Slab in Parallel plate capacitor
In the book Principles of Physics by Resnick Halliday:. The decrease in Potential energy of a parallel plate capacitor due to a dielectric is because the slab would start to oscillate and the energy would transfer back and forth between the kinetic energy of the moving slab and potential energy stored in the electric field.

Forces on Dielectrics
This is a complicated formula, which we will prove in the chapter on capacitors. The following plot shows that when the entire dielectric is just outside the edge, force is greates, and as the dielectric gets pulled in further and further, the force decreases to zero when the dielectric is all the way in, which is at (x=0) in the plot.

Force on dielectric when inserted in charged capacitor
There is a force on the dielectric which pulls it into the capacitor and electric potential energy is converted into kinetic energy of the dielectric. When the dielectric reaches the static equilibrium position it has kinetic energy and will overshoot the static equilibrium position and eventually end up at rest jest outside the capacitor on the other side from where it started. …
