the four particles form a square of edge length a = 4.60 cm and have charges q1 = 11.2 nC, q2 = -11.9 nC, q3 = 7.64 nC, and q4 = -10.4 nC. What is the magnitude of the net electric field produced by the particles at the square's center
q1 is top left corner
q2 is top right corner
q3 is bottom right
q4 is bottom left of square
q1-------------------------q2
q4-------------------------q3
i calculated E1 = 92459N/C
E2 = 98238
E3=63070
E4=85854
E1*(cos45i - sin45j)
E2* (cos45i + sin 45 j)
E3*(-cos45i + sin 45j)
E4*(-cod45i -sin45j)
I added the i and j components
to get the magnitude Enet
Enet = (29538^2 +(.12024)^2)^.5 = 29538
please help?
