In the circuit shown in the figure, `E = 50.0 V, R = 250 Omega` and `C = 0.500 muF.` The switch `S` is closed for a long time, and no voltage is measured across the capacitor. After the switch is opened, the voltage across the capacitor reaches a maximum value of `150 V`. What is the inductance `L`?
