Homework Statement
Point charges +q and -q are placed at +50 cm and -50 cm on the x-axis, respectively. Is the electric field at the origin (halfway between the charges) zero or nonzero? If nonzero, which direction does it point?
Homework Equations
The Attempt at a Solution
Well I know the charges will be attracting each other because they are opposite in polarity. I'm not sure if the electric field will be zero or non zero. I do know that if the charges were the same polarity, then the midpoint in the middle would both be zero. Please help me figure this one out completely.
