Question
Two bars, each 30.0 cm long, and each having a resistance of 2.00 Ohm, are connected to a 1,500 V battery, as shown. The bars are attached to each other with 3 insulating springs, each having a spring constant of 9.00 N/m. The two bars are initially at rest, 4.00 cm apart. The switch is closed, and then opened. Assume there is no friction anywhere in the system. (Note: One can define an equivalent spring constant for the system equal keq = k1 + k2 + k3 = 3[9.00 N/m] = 27.0 N/m.) How far will the two bars be from each other when the switch is closed? After the switch is open, what is the closest the two bars will get to each other? After the switch is open, what is the farthest the two bars will get from each other? Describe the motion of the two bars at time, t, after the switch is open.

The bars are connected to a 1,500V battery, as shown, and they are initially 4.00 cm apart.Explanation / Answer
I was able to find the equivalent spring constant of 27N/m since there are 3 springs. After that, I just don't know how to proceed. I think it's supposed to deal with Gauss Flux.
