The circuit in figure consists of two identical parallel metal plates connected by
identical metal springs to a 100 V battery.
The surface area of one plate is 1778 m². With the switch open, the plates are
uncharged, and separated by a distance
d = 10 mm. When the switch is closed, the distance between the plates decreases
by a factor of half. What is the spring constant, in Newton/meter, for each spring?
E, = 9 x 10-12 C² /Nm²
