A point charge q1:-4.00 nC is at the point x=0.600 meters, y=0.800 meters, and a second point charge q2:+6.00 nC is at the point x=600 meters, y=0 .
a) Calculate the magnitude of the net electric field at the origin due to these two point charges.
Express your answer in newtons per coulomb to three significant figures.
b) What is the direction, relative to the negative x axis, of the net electric field at the origin due to these two point charges.
Express your answer in degrees to three significant figures.
[tex]\phi[/tex]= _________ (up from the negative x axis)
The Attempt at a Solution
I tried calculating E1 and E2 and added them both to get E but my answers are wrong
