Answer: A point charge q1 = -4.00 nC is at the point x =
Chapter 21, Problem 21.48(choose chapter or problem)
A point charge q1 = -4.00 nC is at the point x = 0.600 m, y = 0.800 m, and a second point charge q2 = +6.00 nC is at the point x = 0.600 m, y = 0. Calculate the magnitude and direction of the net electric field at the origin due to these two point charges
