1. The problem statement, all variables and given/known data There is a uniform electric field, E = 270 N/C, parallel to the xz plane, making an angle of 32o with the positive z axis and an angle of 58o with the positive x axis. A particle with charge q= 0.475 C is moved from the point (xi = 2.0 cm, yi = 0, zi = 0) to the point (xf = 8.5 cm, yf = 6.0 cm, zf = -5.5 cm). How much work is done by the electric field. 2. Relevant equations W = qE.d 3. The attempt at a solution The only change in distance I need is parallel to the electric field in the x-z plane. I have no idea how to find the distance. This is what I tried. d = (0.055m)2+(0.065m)2 = 0.085 m Then I believe it's a matter of substituting this into the above equation with the angle which I also don't know how to find. Some guidance would be appreciated thanks.
