The time constant in an RC circuit is a characteristic time for the circuit. It’s a way to measure and compare how fast it takes for the current in the circuit to decrease once the switch is closed. A long time constant implies a slow decay; a short time constant, a rapid decay. Once the switch is closed, the current in the circuit will begin to decline. What is the time constant for this RC circuit, where the capacitor is 5.0 μF and the resistor is 3.0 Ω? Show your work or explain your reasoning.

Consider the following set up of three charges (A, B, and C) aligned horizontally as shown. On your paper, draw the force diagram for charge C to show the electric forces exerted on charge C by charges A and B. Label each accordingly on your diagram. The direction of the net electric force on charge C points to the [direction].
