A point charge q1=?4.00nC is at the point x=0.600 meters, y=0.800 meters, and a second point charge q2=+6.00nC is at the point x=0.600 meters, y=0.
Calculate the magnitude E 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.
