(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two charges Qa = 2 µC and Qb = -2 µC are placed on the x-axis with a separation of a = 21 cm.

(a) Find the net electric field at point P, a distance d = 13 cm to the left of charge Qa.

2. Relevant equations

E=F/q=kq/r^2

3. The attempt at a solution

I tried plugging into the above equation (each point separately) then summing them, but I just cannot seem to find the correct answer.

Thanks for the help.
