This has four parts which has task to find unknown voltages in each case, operational amplifier in this task need to find various unknown voltages. The key foundation in this question is that amplifier are considered to be ideal. In question 2nd we have asked to calculate gain for two stage amplifier. Computation is involving finding gain for both stages and finally we end up in calculation of overall gain.
