Cathode-ray tubes (CRTS) are often found in oscilloscopes and computer monitors. In (Eigure 1) an electron with an initial speed of 6.70x10° m/s is projected along the axis midway between the deflection plates of a cathode-ray tube. The potential difference between the two plates is 24.0 V and the lower plate is the one at higher potential.
