A transistor is operated in common-emitter configuration at $\displaystyle \mathrm{V}_{\mathrm{c}}=2 \mathrm{~V}$ such that a change in the base current from $\displaystyle 100 \mu \mathrm{~A}$ to $\displaystyle 200 \mu \mathrm{~A}$ produces a change in the collector current from $\displaystyle 5$ mA to $\displaystyle 10$ mA. The current gain is :
