Moving Charges and Magnetism Test

Directions For Questions

Two long straight conducting wires with linear mass density $$'\lambda'$$ are suspended using cords so that both of them are horizontal and parallel to each other at a distance $$'d'$$ apart. The back ends of the wires are connected by a low resistance slack wire. A charged capacitor is now added across the wires such that its positive terminal is connected to far end and negative terminal is connected to near end as shown in figure. The capacitance of the capacitor is $$C$$. These connections are also made by slack wires. Assume that time to discharge is negligible. Initial charge on capacitor is $$Q_0$$.
