A change of 0.04 volts takes place between the base and the emitter when an input signal is connected to the common emitter transistor amplifier. As a result, 20 \\mu \A change takes place in the base current and a change of 2 { \mA} takes place in the collector current. The input resistance and {\AC} current gain are ______

Correct Answer is : 2 kΩ and 100
