0 1 . 4 In 1897, J J Thomson determined a value for the specific charge of an unknown box
particle.
The unknown particle is now known to be the electron.
Describe one method to determine the specific charge of the electron.
Your answer should include:
a description of the apparatus used and the measurements made
a description of how the specific charge can be determined using these
measurements
an explanation of the conclusion made by Thomson from the value that he
determined.
