the equation I listed is for electric fields. My thought was since their are 2 charges I should add a 2 in front of the q. I guess their is some new equation I wasn't taught...?
Homework Statement
A proton located several proton diameters away from a small charged object carrying charge q is subject to an electric field of magnitude E. As the proton moves a distance d along the x-axis away from the object, the electric field magnitude drops to E/4.
If the charged...
