A point charge Q1=-2µC is located at x=0, and a point charge Q2=-8µC is placed at on the x -axis of a cartesian coordinate system.The goal of this problem is to determine the electric field,E(x)=E(x)x^ , at various points along the -axis.
(a)What is E(x) (in N/C) for x -68.0 m ?
What is E(x) (in N/C) at -0.42 m?
What is E(x) (in N/C) at 65 m?
