Two parallel plates separated by distance of 10cm have a potential difference of 20V between them. The plates are held in a horizontal position with the negative plate above the positive plate. An electron is released from rest in the upper plate. Find the time the electron takes to reach the lower plate?

A group of physics students reproduce the Millikan experiment to suspend a charged oil drop (m = 9.7 micrograms) suspended between two parallel plates that are separated by 1.85 cm (as shown). If the students apply an electric potential difference of 11.34 V across the plates, determine the charge on the oil droplet.

Calculate the speed of a proton and an electronic after each particle accelerates from rest through a potential difference of 355V.

an evacuated tubes a potential differences of v=0.24 Kv to accelerate electrons which then hit a copper plate and produce x rays   Write an expression for the non-relativistic speed of these electrons v in terms of e, AV, and m, assuming the electrons start from rest

As shown in Figure 1, two parallel plates have a potential ditterence of 12 V and are held a distance of 0.001m apart. A free charge held near the positive plate moves to the right, as shown, when it is released. It then moves through an opening in the negative plate on the right. 12V (a) Is the particle a proton or an electron? (b) What is the energy (in Joule) as it leaves the right plate? (c) How fast is it moving when it reaches the negative plate? (d) What are the magnitude and the direction of the electric field between the plates?

Two large aluminum plates are separated by a distance of 2.0 cm and are held at a potential difference of 195 V. An electron enters the region between them at a speed of 3.2 × 105 m/s by passing through a small hole in the negative plate and continues moving toward the positive plate. Assume the electric field between the plates is uniform. 1. What is the electron’s speed, in meters per second, when it is 0.1 cm from the negative plate?  2. What is the electron’s speed, in meters per second, when it is 0.5 cm from the negative plate?  3. What is the electron’s speed, in meters per second, when it is 1.0 cm from the negative plate?  4. What is the electron’s speed, in meters per second, when it is 1.5 cm from the negative plate?  5. What is the electron’s speed immediately before it strikes the positive plate?

A particle with mass M and charge —q is projected with speed V into the region between two parallel plates as shown. The potential difference between the two plates is V and their separation is d.

The uniform electric field between two charged parallel plates has a magnitude of 4400 V/m (note that 1 V/m = 1 N/C). If the plates are separated by 0.0100 m and an electron is released from the far negative side of the gap, what will the electron's kinetic energy (in eV) and speed be when it just reaches the positive plate? Note that the electron charge = -1.602 x 10-19 C and the electron mass = 9.11 x 10-31 kg. KE V= ev m/s
