## Homework Statement

Find the angle that

(Consider vectors above the x axis to make positive angles and vectors below the x axis to make negative angles.)

## Homework Equations

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.
