7. [6 pts] After placing the CRT into the center of the solenoid, you start increasing the current steadily until you find the value of current needed to calculate the charge-to-mass ratio of the electron. How can you tell that the value shown on the power supply is the right one to use? (What will the "signal" look like on the CRT screen?)
