1. Homework Statement [/b]
Problem - Compute the potential difference between the points (4,6,3) and (8,1,6) due to a constant electrostatic field given by E = (2 ihat + 7 jhat + 12 khat) N/C. distance in meters


Homework Equations



Fq = qE

Vr = Keq1/(r-r1)

Fq = (Kq1 (r-r1))/(r-r1)3

The Attempt at a Solution



I can't figure out how to solve.

Currently I combined the two points to find the vector magnitude and then found the maginute of E. then plugged into the Fq = qE problem to solve for q. Then plugged into the Vr equation. I don't believe this is correct though and should be using the third equation as well.

Try
[tex] V = - \int \mathbf{E} \cdot d \mathbf{l}[/tex]

The class is not calculus based. It has to be worked by algebra.
