Consider two point charges located on
the x axis: one charge, q1 =
-13.5 nC , is located at x1 =
-1.715 m ; the second
charge, q2 = 32.0 nC , is at the
origin (x=0.0000).
What is the net force exerted by these two charges on a third
charge q3 = 47.5 nC placed
between q1 and q2 at x3 =
-1.155 m ?
Your answer may be positive or negative, depending on the
direction of the force.
Express your answer numerically in newtons to three significant
figures.
