How do you approach questions like these:

A beam of electrons traveling with a speed of 3.0 x 10^7 m/s enters a uniform, downward electric field of magnitude 2.0 x 10^4 N/C between the deflection plates of an oscilloscope, as shown in the figure. The initial velocity of the electrons is perpendicular to the field. The plates are 6.0 cm long. Calculate the magnitude of the change in velocity of the electrons while they are between the plates.
