1-1 In the cathode ray tube, an electron is initially at rest (approximately) and is accelerated by a force produced by an electric field. However, in lab you will only know the positive change in voltage Va (really "Va") of the plates through which the electron is accelerated. What simple formula using Va, q and W (work) can you write to relate the work done on the electron to the change in voltage of the apparatus
