**1. Homework Statement**

The electric field in a region is given by E=2x^2 i +3y j where the units are in V/m. What is the potential difference from the origin to (x, y) = (2, 2) m?

**2. Homework Equations**

E = -gradient of V

**3. The Attempt at a Solution**

- derivative of the x-component: 2/3 x^2 from 0 to 2 = -16/3 x

- derivative of y-component: 3/2y^2 from 0 to 2 = -6 y

And then I added them for −11&1/3 V

But this wrong. I'm shown the correct answer is -27 & 1/3 V

Any tips on how that could be? Thanks !
