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

Find the electric field at the center of a square having side = 1m and having the following charges at each corner:

Q1:-1 x 10^-6

Q3: -2 x 10^-6

Q2: 2 x 10^-6

Q4: -1 x 10^-6

(Q1 is upper left corner, Q2 is upper right, q3 is lower left and Q4 is lower right)

2. Relevant equations

E= k*q/r^{2}

3. The attempt at a solution

I used the equation to found the electric field for each of the charges (Q1: -18000, Q2: 36000, Q3: 36000, Q4: -18000) . But now I don't know what to do
