2.19 An inverting op-amp circuit for which the required gain is −50 V/V uses an op amp whose open-loop gain is only 500 V/V. If the larger resistor used is 100 k, to what must the smaller be adjusted? With what resistor must a 2-k resistor connected to the input be shunted to achieve this goal? (Note that a resistor R a is said to be shunted by resistor Rb when Rb is placed in parallel with Ra.)
