In the image provide these exists two parallel plates call A and B the length of both being 5 centimeters and both separated from each other with a distance of 4 centimeters. An electron enters 1 cm above plate B and it is traveling horizontally at speed of 1x10^6 m/s. VA = 20 V and VB = 10 V are the plate potentials, respectively. A) What is the electrical field (vector) between the plates? B) What is the electric potential V at the entry point of the electron and its initial potential energy? C) The electron eventually find the speed one of the plates, find out out witch one and the speed of the electron before the impact. D) What is the location along the place where the electron makes impact (take x =0 as the left edge of the plates). OFocus 81 F 0.
