plate is 3.0 cm and the distance of the screen to the deflecting plate is 1.0m (x axis). With
the applied electrical field of 2.1 x10° V/m, image of the electron beam is observed at the
height of 36 cm (y axis). With the applied magnetic field of 1.2 x 10° T, the image is seen at
the center of the screen with no deflection.

b) Find the q/m for the electron.
c) If the length of the deflecting plate would be 2.5 cm, where would the beam is observed?
d) Assuming mass of the electron is known and the value is m=9.1x1031 kg, find the rest
Energy, total energy and the kinetic energy of the electron.
e) Find the relativistic momentum of the electron.
Hint: Use equations in Thomson's experiment for a, b and c. Use relativistic kinematic
equations for d and e by using the velocity you obtained in a.

- For years, exposure to ultra-violet radiation from prolonged time in the sun has been the major identified cause of skin cancer. New research is showing that ultra-violet is not the only type of radiation from the sun that can increase the risk of skin cancer. Rates of skin cancer among pilots are twice that of non-pilots, but the glass used in planes blocks most the ultra-violet radiation. Pilots are also exposed to x-rays from the sun during flight. The x-rays that pilots are exposed to in one day of work are equivalent to a chest x-ray. Although getting an x-ray for medical reasons is believed to be safe, researchers believe that the frequent exposer that pilots experience increases their risk for skin cancer.
