Three negative point charges lie along a line as shown in (Figure 1) . Point P lies 5.00 cm from the q2= -3.50x10^-6 charge measured perpendicular to the line connecting the three charges. Assume that q1=q3=-6.00x10^-6

Find the magnitude of the electric field this combination of charges produces at point P. Express your answer in newtons per coulomb to three significant figures.
