Question

A point charge of -14nC and +12nC is located 12cm along the x-axis.  Determine the magnitude and direction of the electric field intensity at point P at the mid-point and 8cm perpendicular from the x-axis:

p
                  |
                  | 8.0cm
                  |
                  |
     -14nC.---------------. 12 nC
            6cm      6cm

Please help getting mixed up with the theory!  Thanks!!!!
