Math Problem Statement
Conventional TV tube. Early television sets depended on images being built up on the screen by the deflection of electrons directed toward the screen from the rear of the tube. The figure below shows such a deflection system. The length of the plates is 2.59 cm and the deflecting electric field between the two plates is 9.00 × 105 N/C vertically upward. If an electron enters the space between the plates with a horizontal speed of 3.86 × 10' m/s, what is the vertical displacement of Ay at the end of the plates?
