ANALYSIS FOR CALCULATING (e/m): 1. Calculate B from equation (2) for each value of I. 2. Solve equation (1) for B as a function of (VR). 1/2 2V B-(2) B= (3) elm 3. For each of the three accelerating voltages, plot B on the vertical axis and (IR) on the horizontal axis. The graphs should be straight lines. 4. Determine the slope for each graph. AB Slope = (4) R 5. For each of the three accelerating voltages calculate e/m as follows. AB (5) (25) Slope H 2V m (slope) = A
4. Determine the slope for each graph. AB Slope =- (4) R 5. For each of the three accelerating voltages calculate e/m as follows. 1/2 AB 2V (5) = Slope elm 27 (6) m (slope)? 6. Compare the experimental value to the theoretical value of e/m = 1.759 x 10¹ C/kg and find the percentage error for V-180, V-200 V and V = 220 volts. e/m R A
