In a certain region an electric potential V is present. An unknown charge Q is moved around this region between points at potential difference AV. A physicist measures the change in the potential energy AU as the charge is moved. The table below shows the data of the measurements. The unit for AV are MV (mega-Volts), the units for AU are kJ (kilo-joules). Δν 57.1 29.9 16.7 9.97 8.55 8.32 6.52 6.87 AU 362.8 157.6 124.3 55.3 48.8 53.9 37.9 47.3 You want to find the value of the unknown charge Q in mC. Since AU = QAV make the plot y=mx where y=AU and x=4V. Use Excel, calculator or whatever you prefer. From the slope of the plot, calculate Q.
