**1. The electric potential in a certain region is:**

V = ax

V = ax

^{2}+bx +cwhere a = 13V/m

^{2}

b = -16V/m

c = 59 V

Determine the postion where the electric field is zero. Answer in units of m.

## Homework Equations

E = -[tex]\nabla[/tex]V

## The Attempt at a Solution

I know that the Electric Field is the negative gradient of the potential function. I then find that the partials with respect to y and z are zero. Then I find the partial with respect to x is: E

_{x}=-13x+16

Then find the zero to be about 1.23. But it is apparently incorrect. Any help would be appreciated.
