A simple and common technique for accelerating electrons is shown in the figure below, where a uniform electric field is created 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 continue moving.(a) Calculate the acceleration of the electron if the field strength is 7.53 x 104 N/C.

Singly-ionized helium contains two protons and one electron (there are also neutrons, but they have net zero charge and are not pertinent to this problem). Suppose the electron is located a distance of 2.65 × 10^-11 m from the nucleus. Place the nucleus at the origin of your coordinate system and the electron on the positive-x axis. What is the position on the x-axis at which the electric field is zero?
The classic Millikan oil drop experiment was the first to obtain an accurate measurement of the charge on an electron.

Two horizontal parallel plates are separated by a distance of 174 mm creating an electric field of 23 μN/C directed north. An electron is place halfway between the two plates with and fired with initial velocity 58 m/s from the horizontal. Calculate the time it takes for the electron to land at the positive plate and its speed before hitting the plate. Provide an Illustration and answer in GRESA format.
A simple and common technique for accelerating electrons is shown in the figure below, where a uniform electric field is created 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 continue moving. O (a) Calculate the acceleration of the electron if the field strength is 7.96 x 10¹ N/C. m/s² (b) Why will the electron not be pulled back to the positive plate once it moves through the hole? O The force of gravity is too strong. The other side of the positive plate also has a negative charge. There is no field outside the plates.
In a typical television or in an older computer picture tube (CRT), the electrons that strike the screen to form an image are accelerated between two charged plates that have a potential difference of 2.5×104 V. The plates are separated by a distance of 1.3 cm. Assuming that there is a uniform electric field between the plates, calculate the strength of the field.
