A moving coil galvanometer allows a full scale current of $\displaystyle 10^{-4} \mathrm{~A}$. A series resistance of $\displaystyle 2 \mathrm{M} \Omega$ is required to convert the above galvanometer into a voltmeter of range $\displaystyle 0$-$\displaystyle 5$ V. Therefore the value of shunt resistance required to convert the above galvanometer into an ammeter of range $\displaystyle 0-10 \mathrm{~mA}$ is :
