The figure below shows an electron passing between two charged metal plates that create an 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 5.00 ✕ 106 m/s, and the horizontal distance it travels in the uniform field is 10.0 cm. (a) What is its vertical deflection in meters? 3.52e-3 Correct: Your answer is correct. m...
