    This is sort of a trick question, because it's really very easy.

    Ask yourself : is there any feedback in this circuit ? Feedback is when the output is fed back in part to the input. Does it happen here ?

    What happens when there is no feedback in an opamp ? Hint : Comparator. Look this term up.

    Find the voltage at the negative input. Hint : Voltage divider. Is it different from that at the positive input ?

    What happens to the output ? Hint : Saturation.
