Hi,

I am a little bit confused with how to find the electric potential everywhere.

I have this electric field:

E=x(x^2)+y(y^2)+z(2*z) wherex,y,zare unit vectors.

Find the electric potential everywhere?

I know that V=-[integral] E*dL

But the fact that it is said "everywhere" confused me. I understand better when everywhere is used with two concentric cylinders or spheres but in the plane like this ..??

I guess I just have to do the integration without boundary.

Please, can someone tell me what I can do?
