Instructiоn: Input numericаl vаlue оnly; nо unit.  Keep two decimаl points for your numerical answer. Example: -3.14,  -314.51, 3.14, 314.51 A charge of +1×10-8 C is at the origin and a charge of -2 ×10-8 C is on the y-axis at y = +4 m. Point A is on the x-axis at x = +4 m. What is the electric potential at point A, with unit in volts? Remember that the potential is zero at infinity.
