Capacitor inserted into thick metal plate

Let us imagine that we have a capacitor in which the plates are horizontal; the lower plate is fixed, while the upper plate is suspended above it from a spring of force constant (k). We connect a battery across the plates, so the plates will attract each other. The upper plate will move down, but only so far, because the electrical attraction ...
