I found them. I circled them in red:

Seriously though, "Find D1 and D2" is not a question. What aspects of D1 and D2? D1 and D2 are just diodes. Do you want the current flowing through them? Power dissipated? There are many measurements that can be taken of D1 and D2. Asking to "find D1 and D2" is not a complete question.

And your answer is ??
And how can Vx = 0V if you assumed that both diodes are ON and notice that D2 cathode is at 2V.

Yes I meant the current flowing through d1 and d2

What do you mean when you say, "Vx=0 for short circuit"?

You indicate that Vx is the voltage at the node at the bottom of the 1 kΩ diode. Why would the voltage there ever be 0 V?

What model are you using for your diodes?

Saying, "I1 = 1" is fundamentally incorrect. '1' is a number, it is not a current. You have a current of '1 mA', so you need to say that "I1 = 1 mA"

Track your units -- the payoff is huge.

You just made my day lol
