75. A flat capacitor with square plates of 10 cm x 10 cm located at a distance of d = 2.0 mm from each other is connected to a constant voltage source U = 750 V. A glass plate 2 (see figure) is pushed into the space between the plates , 0 mm with a constant velocity υ = 40 cm / s. What current I flows in this circuit?
