I am trying to solve this problem:(adsbygoogle = window.adsbygoogle || []).push({});

The electric potential in a region of space is V = 210x^2 - 270y^2, where x and y are in meters. Find the E-field at (3m, 1m)

So I started with:

[tex]E = \frac{V}{d}[/tex]

so then I plugged x and y into the electric potential equation and got

V= -200 Volts

Then I multiplied it by the distance [tex]d=\sqrt{x^2+y^2}[/tex]

Unfortunately this is not the right answer. Perhaps someone could show me where I went wrong

Thanks
