The electric potential as a function of x, y is given by V=5(x^2-y^2) V. The electric field at a point (2,3) m is ____ V/m.

The electric potential as a function of $\displaystyle x, y$ is given by $\displaystyle V=5\left(x^2-y^2\right) \mathrm{V}$. The electric field at a point $\displaystyle (2,3) \mathrm{m}$ is $\displaystyle \_\_\_\_$ V/m.
