An electron passing between two charged metal plates that create a 100 N/C vertical electric field perpendicular to the electron's original horizontal velocity. (These can be used to change the electron's direction, such as in an oscilloscope.) The initial speed of the electron is 3.00 x 10^6 m/s, and the horizontal distance it travels in the uniform field is 4. 00 cm. a. Draw a free body diagram depicting the problem.​
