Two point charges, q1 = +20.0 nC and q2 = +10.0 nC, are located on the x-axis at x = 0 and x = 1.00 m, respectively. Where on the x-axis is the electric field equal to zero? Two electric charges, q, = +20.0 nC and q2 = +10.0 nC, are located on the x-axis at x = 0 m and x = 1.00 m respectively. What is the magnitude of the electric field at the point x = 0.50 m, y = 0.50 m
