The Capacitor Shown in the Circuit in the Figure Is $\mathrm { S }$

Short Answer

The capacitor shown in the circuit in the figure is initially uncharged when the switch $\mathrm { S }$ is suddenly closed, and the battery is ideal. After one time constant has gone by, find (a) the current through the resistor and (b) the charge on the capacitor. Assume that the numbers shown are all accurate to two significant figures.
