Two charges are placed on the x axis. One charge (q1=+8.45 mC) is at x1=+2.55 cm and the other (q2=-21.4 mC) is at x2=+9.01 cm. Find the magnitude of the net electric field at x=6 cm.(adsbygoogle = window.adsbygoogle || []).push({});

I used this equation:

(x is in cm)

(N/C) = {(k * 8.45*10^-6) / [(x+2.55)^2 / 100]} - {(k * 21.4*10^-6) / [(x-9.01)^2 / 100]}

and my solution is not correct.
