Use the slope calculated and Equation #4 to calculate the mass-to-charge ratio (m/q) and record this value in your datasheet. **Note that all other variables in Equation #4 (except r and I) are constants for this experiment. The slope of the graph is 3.09 x 10-3 which is the relationship: r2 vs 1/I2. The constants are: V= 150 V, a = 0.158 m, N= 130, Mu0= 4pi x10-7. The image shows what equation should be used.**
