Cathode-ray tubes (CRTs) are often found in oscilloscopes and computer monitors. In the figure (Figure 1) an electron with an initial speed of 6.70×106m/s is projected along the axis midway between the deflection plates of a cathode-ray tube. The potential difference between the two plates is 26.0V and the lower plate is the one at higher potential.a)What is the magnitude of the force on the electron when it is between the plates?What is the direction of the force on the...
