Evaluation and results 1. From the data given in table (1) and with the help of eq. (8), Draw (V) vs Ic? and use the graph (1) to find (e/m) with the estimated error in the value. The slope = CA) (K2r2)]. Where K= 7.80 x 104 Tesla/A and r=4.0 cm or any fixed value you have used in your experiment 2. Find the percentage error of the resulted (Measured) value as compared with the accepted value of e/m. The accepted (Theoretical) value of the charge-to-mass ratio, e/m, is 1.76 x 10" C/kg |Accepted value - Measured value Percentage Error = * 100% Accepted value 3. From the data given in table (2) and with the help of eq. (8), Draw (VA) vs r and use graph (2) to find (e/m) with the estimated error in the value. The slope = L ) (K?12)] = . Where K = 7.80 x 10* Tesla/A and Ic fixed at that value when Va =300V and having a maximum beam orbit diameter or any fixed value you have used in your experiment. 4. Find the percentage error of the resulted value as compared with the known value of (e/m). 5. Find the percentage error of the resulted value from this graph (2) as compared with the resulted value of e/m found from graph (1) in step 1. 6. Discuss the all the main sources of errors for both methods. Give any practical suggestions to reduce the error and improve the results.
