A transistor is used in common-emitter mode in an amplifier circuit. When a signal of \( 10 \mathrm{mV} \) is added to the base emitter voltage, the base current changes by \( 10 \mu \mathrm{A} \) and the collector current changes by \( 1.5 \mathrm{~mA} \). The load resistance is \( 5 \mathrm{k} \Omega \). The voltage gain of the transistor will be
