How does the output voltage of an Op-Amp swing to keep the inverting terminal at virtual ground in this circuit?

Vout should be -10 volts according to the voltage gain equation of inverting amplifier which is based on the rule of op amp that A is at zero volts. Here the output is grounded and the node A becomes 0.91 V (i.e) it is not at virtual ground. What would happen now? would the output voltage change? if it does change I am having a hard time understanding how it would?
