You can reasonably assume that currents can flow from an input (Va in your diagram) and from the op-amp output (Vo in your diagram). This means you can assume current does not flow...
As V1(non inverting terminal) is grounded. That means the output will be zero, because the amplification of zero by any factory is zero itself. regards.

dear see attached file... I hope it's helpful for you dear..

see attached solution. output will be 6 coz Vb= Va

while calculating potential at A, why do we add up all the current to zero? current must flow down to ground?

non inverting case..I used this formula(or concept)..
