## Homework Statement

What is the value of V2 in terms of Vos?

## Homework Equations

## The Attempt at a Solution

In the class, we were told that this is just a non-inverting amplifier, thus V2= Vos x (R2/R1+R2).

However, I want to work out the solution by applying nullator hypothesis (voltage difference between the two op amp inputs is 0) only, without realising that the top part is a potential divider.

Is it correct to assume that the voltage across R1 is Vos? That way, I can get the current i to solve for the voltage across R2.
