Consider two point charges located on the x axis: one charge,
q1= -19.0 nC , is located at x1 = -1.700 m; the second charge, q2
q= 40.0 nC , is at the origin (x = 0).
What is (Fnet3)x the x-component of the net
force exerted by these two charges on a third charge q3 = 54.5 nC
placed between q1 and q2 at x3=
-1.160 m ?
Your answer may be positive or negative, depending on the
direction...
