Electric Field of Two Charges : 15.0 points
A point charge is located at x=0, and a point charge is placed at on the -axis of a cartesian coordinate system.The goal of this problem is to determine the electric field, , at various points along the -axis.
(a)What is (in N/C) for -68.0 m ?
What is (in N/C) at -0.42 m?
What is (in N/C) at 65 m?
(b) At what point (apart from ), is ? Express your answer in meters.
