Here, IC=4.9/5K=0.98mA
α = IC/IE .So,
IE=IC/α=0.98/0.98=1mA.
IB=IE-IC=1-0.98=0.02Ma.

CB configuration, the value of VCB is the control voltage that is applied to the base terminal of the transistor. This voltage determines the amount of current flowing through the base-emitter junction and ultimately controls the amplification of the transistor. In CB configuration, the base terminal is common to both input and output, while the collector terminal is connected to the power supply and the emitter terminal is connected to the ground.
