Instructiоn: Input numericаl vаlue оnly; nо unit. Keep two decimаl points for your numerical answer. Example: -3.14, -314.51, 3.14, 314.51 Two point-charges, q1 and q2, are positioned along the x-axis. q1 has a charge of -3×10-9 C, and q2 has a charge of +5×10-9 C. q1 is situated at the origin, while q2 is located at x = +2 m. Point A is positioned on the x-axis at x = -2 m. What is the magnitude of the electric field at point A, with unit in N/C? Note that magnitude is positive.
