Between the plates of a parallel-plate capacitor there is a metallic plate whose thickness takes up `eta = 0.60` of the capacitor gap. When that plate is absent the capacitor has a capacity `C = 20 nF`. The capacitor is connected to a `dc` voltage source `V = 100 V`. The metallic plate is slowly extraced from the gap. Find :
(a) the energy increment of the capacitor,
(b) the mechanical work performed in the process of plate extraction.

Inside a parallel-plate capacitor there is a plate parallel to the outer plates, whose thickness is equal to eta = 0.60 of the gap width. When the plates is absent the capacitor cpaacitance equals c = 20 muF . First, the capacitor was connected in parallel to a constant voltage source producting V = 200 V , then it was disconnected for it, after which the plates was slowly removed from teh gap. FInd the work perfomed during the removel, if the plate is (a) made of metal, (b) made of glass.
