The lower plate of the capacitor is fixedly fixed on an insulating stand, and the upper plate is suspended on an elastic spring. Distance between uncharged plates d0. When voltage U1 is applied to the capacitor, the distance between the plates is d1; when voltage U2 is applied, the distance is d2. Determine the voltage ratio n = U2/U1 (Fig.).
