Question

In the circuit in the figure, two identical parallel metallic plates are connected to a 100V battery by an identical metallic spring. In the open state, the plates are unloaded, the span d = 4mm and the surface of one plate is 1778 m ^ 2. When the switch is turned off, the distance between the plates is reduced by 0.5 times. What is the spring constant of each spring in units of Newton / meter?
