An inductor of inductance $\displaystyle 10$ mH having resistance of $\displaystyle 100 \Omega$ is connected to battery of E.M.F. $\displaystyle 1.0$ V through a switch as shown in the figure below. After switch is closed, the ratio of instantaneous voltages across the inductor when the current passing through it is $\displaystyle 2$ mA and $\displaystyle 4$ mA is $\displaystyle \_\_\_\_$.
