An op-amp has an open-loop gain of 200 V/V. If this op-amp is usedto build an inverting amplifier with an absolute gain of 50V/V:
(a) What must the smaller resistor be adjusted to, if the largerresistor is 100 k?
(b) If the smaller resistor is to be formed by a pair of resistorsin parallel, with what resistor must a 2-k resistor be connected in parallel at theinput to achieve the same gain?
