# Electric potential at point from origin

rlaulusa

## Homework Statement

In the presence of a uniform electric field, E=-6.0 i + .8 j + 3.42 k N/C, assume that the electric potential is -5V at the origin of the coordinate system, and determine the electric potential at the point 2.7 i -2.7 k.

Here's what I've done so far
$$\Delta$$V=V(2.7, 0, -2.7) - V(0, 0, 0,) = $$\int$$Eds
=-($$\int$$$$^{2.7}_{0}$$Exdx + $$\int$$$$^{0}_{0}$$Eydy + $$\int$$$$^{-2.7}_{0}$$Ezdz)
=-($$\int$$-6.9dx + $$\int$$.8dy + $$\int$$3.42dx)
=3.48 V

But I don't think this is correct. We did a problem similar to this in class where we had to define the path we were taking, but I wasn't sure how to do that in this problem.

Thanks!
