GATE EC 2006 Set 1 Q41 — Op-amp Circuits

For the circuit shown in the following figure, the capacitor $C$ is initially uncharged. At $t=0$, the switch $S$ is closed. The voltage $V_{C}$ across the capacitor at $t=1$ millisecond is

In the figure shown above, the $\text{OP AMP}$ is supplied with $\pm 15 \mathrm{~V}$ and the ground has been shown by the symbol $\nabla$.
