(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What is the magnitude of the electric field at the point (3.00[tex]\hat{i}[/tex] - 2.00[tex]\hat{j}[/tex] + 4.00[tex]\hat{k}[/tex])m if the electric potential is given by V = [tex]2.00xyz^2[/tex], where V is in volts and x, y, and z are in meters?

2. Relevant equations

To calculate the field from the potential, [tex]E_{s}=-\delta V/ \delta s[/tex] (ie [tex]E=-dV/ds[/tex] for each component).

3. The attempt at a solution

[tex]E_{x}=-dV_{x}/dx[/tex]

[tex]E_{y}=-dV_{y}/dy[/tex]

[tex]E_{z}=-dV_{z}/dz[/tex]

I don't know what they mean by [tex]2.00xyz^2[/tex].
