A 5.40 nC point charge is on the x axis at x = 1.25 meter. A second point charge Q is on the x axis at -0.625 meter.
A) Find what must be the charge Q for the resultant electric field at the origin to be 50 N/C in the +x direction?
B) Find what must be the charge Q for the resultant electric field at the origin to be 50 N/C in the -x direction?
