three equal and positive charges q are located equidistant from the origin as shown http://s966.photobucket.com/albums/ae146/acherentia/?action=view¤t=directionofanelectricfield.jpg . Is the direction of the electric field at the origin a) along x, b)along -x, c) along +y d) along -y
The electric field is directed outward away from Q when Q is positive.
The Attempt at a Solution
Do the field lines along the x-axis emerging from the charges on the x-axis cancel or enhance each other at the origin?
Do I have to do vector addition on the x-axis to solve this problem?
