Convert galvanometer into ammeter/voltmeter

For an experiment that Omar is performing, he needs to measure voltages up to $1.4\text{V}$‍. He has a galvanometer having resistance $G=2.0\mathrm{\Omega }$‍ and a range of $0-50\mu \text{A}$‍. He wants to use the galvanometer for this measurement.

What is the magnitude of the resistance that Omar attach to the galvanometer?$\begin{array}{rl}& \\ & \end{array}$‍ Note: Report your answer correct to two significant figures

$\times {10}^4\mathrm{\Omega }$‍
