A transistor is used in common-emitter mode in an amplifier circuit. The base current and the collector current is changed by 30 mA and 3 rnA respectively when a signal added to base-emitter voltage. If the voltage gain is 600 and the load resistance is 10 kΩ, then the magnitude of signal added to base-emitter voltage is
