Answer
When V1 is less than V2, the op-amp will output a negative voltage. This happens because the non-inverting input (+) receives a lower voltage than the inverting input (-). Thus, the output state will be low, leading to:
Vout = 0 V (Negative output state)

Answer
In this scenario, when both V1 and V2 are equal, the op-amp will ideally output zero volts. Since there is no difference between the inputs, the output state will be:
