The time constant $\tau$ for an RC circuit is given by $\tau = RC$, where $R$ is the resistance in ohms ($\Omega$) and $C$ is the capacitance in farads (F). Here, $R = 1000 \Omega$ and $C = 2.00 \text{ mF} = 2.00 \times 10^{-3} \text{ F}$. Thus, $\tau = 1000 \Omega \times 2.00 \times 10^{-3} \text{ F} = 2.00 \text{ s}$.
