Question
(9%) Problem 4: A simple and common technique for accelerating electrons is shown in the figure, which depicts a uniform electric field between two plates. Electrons are released, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to pass through. Randomized Variables E 2.35 x 104 NIC Otheexpertta.com A Calculate the horizontal component of the electron's acceleration if the field strength is 2.35 x 104 NYC. Express your answer in meters per second squared, and assume the electric field is pointing in the negative x-direction as shown in the figure.

problem 4)
E = 2.35 *10^4 N/C
let the horizontal component's is a
Using second law of motion
m * a = e * E
9.11 *10^-31 * a = 1.602 *10^-19 * 2.35 *10^4
solving for a
a = 4.133 *10^15 m/s^2
the horizontal component of electron's acceleration is 4.133 *10^15 m/s^2
