**1. Homework Statement**

Ok, i have this problem i am trying to solve and i am stuck.

Q. A uniform Elec. field @ 75N/C is at an angle, 33degrees, relative to the positive X-axis. Find the voltage between the points (.5meters,0) and (0,0).

I started the problem off by using the equation V=Ed; i thought that i could also write the equation as V=Ed(cos theta) due to the field lines not being parallel to the direction of movement.

Im not even sure that is the right way to do taht.

Then in part B is asks to find the value of Y such that the V between (.3 meters, Y) and (0,0) is equal to the same value from A.

I know it would have to be on a perpendicular electric field line running through the first point. Do i just use trig functions to get the unknown sizes for the triangles that can be drawn?

Any help or pointers would be appreciated, thanks.
