Question

An old CRT monitor is being demonstrated. You know that a beam of electrons is directed at the screen by a uniform electric field. The potential difference across the electric field is 24.0V . An electron enters the field with a velocity of 3.20 x10^7 m/s [forward], directly in the middle of the field. The charged plates creating the field are 0.008200 m apart, and each plate is 0.0150m long. Assume the top plate is positive. a) Determine the strength of the field. Be sure to include direction in answer b) How long will it take for the Electron to travel through the field? c) Calculate the magnitude of the electric force acting on the electron while in the field. d) Calculate the displacement of the electron in the vertical direction the moment the electron leaves the field. Assume the middle of the field is the reference (zero) position. please answer quick and all answers to 3 significant digits
