Output current of op-amp of following circuit
You have negative feedback and that means the op-amp will drive its output high or low until the two inputs are at the same voltage. This is how negative feedback works. So if you have 2 volts on the +input then, you must have 2 volts at -input.

This means Ie is 2/R3 etc...

Don't forget that Ie = Ic + Ib.

Can you take it from here?
