In a certain region an electric potential V is present. An unknown charge Q is moved around this region between points at potential difference ΔV. A physicist measures the change in the potential energy ΔU as the charge is moved. The table below shows the data of the measurements. The unit for ΔV are MV (mega-Volts), the units for ΔU are kJ (kilo-joules). You want to find the value of the unknown charge Q in mC. Since ΔU = QΔV make the plot y=mx where y=ΔU and x=ΔV. Use Excel or Libreoffice Calc or what you prefer. From the slope of the plot, calculate Q. 21. What is the unknown charge Q? (mC) (m-milli 10-3)
