Instructiоn: Input numericаl vаlue оnly; nо unit. Keep two decimаl points for your numerical answer. Example: -3.14, -314.51, 3.14, 314.51 Consider a two-dimensional system consisting of two point-charges q1 = +4×10-8 C and q2 = -3×10-8 C. q1 is located at (x, y) = (0, 1 m); q2 is located at (x, y) = (1.5 m, 0). What is the y-component of the net electric field, Ey, at a point located at (x, y) = (0, -1 m)? Express your answer in unit N/C. Note that Ey is positive when directed along the positive y-axis and negative when directed along the negative y-axis.
