1. What is the expected charge to mass ratio for an electron based on the unknown values for the charge and mass of an electron?

2. Comment on the accuracy of your results. Does your results agree with the expected charge to mass ratio for an electron

6. Now you can plug the expression for B (from Question 5) into the expression for 1 from Question 4. After cleaning this up a little, you should have an expression in terms of the 3 values that will be determined during the experiment: V, r², and I. m constant V .2 m note: the constant in this expression is not the same as the constant from Question 5.

For a constant magnetic field (constant current), vary the velocity of the electron (by varying voltage that it accelerates through) and measure the corresponding diameter (in cm) of the curved path that the electron follows. Record your data in Table 1. Using your data and the equation derived in pre-lab question 6, calculate q/m for the electron for each voltage. Compute the average q/m and standard error .
