74. A flat capacitor with a plate width of 20 cm and a distance between them of 2 mm is connected to a current source with an electromotive force of 120 V. Into the space between the plates of a capacitor at a speed of 10 cm / s. push the glass plate with a dielectric constant ε = 6 (Fig.). Determine the amount of current flowing through the galvanometer. Neglect the resistance of the current source and the galvanometer.
