Find the angle that
(Consider vectors above the x-axis to make positive angles and vectors below the x-axis to make negative angles.)
pheta = arctan (Ex/Ey)
tan(pheta) = Ex/Ey
The Attempt at a Solution
I already found that Ex= -2 N/C and Ey= -2 and IEI = 2.83 N/C
So I tried pheta = arctan (-2/-2) = 45 degrees but it's still marked incorrect.
