An electron (mass m = 9.11x10^-31 kg) is released in the uniform field (E = 2.0x10^4 N/C) between two parallel charged plates. The separation of the plates is 1.5 cm. The electron is accelerated from rest near the negative plate. If the gravitational force can be ignored, determine (a) the direction of the electric force acting on the electron; (b) the magnitude of the electric force acting on the electron; (c) the velocity of the electron after 2.0 ns; (d)...
As shown in the figure, an electron is fired with a speed of 3.59 × 106 m/s through a hole in one of the two parallel plates and into the region between the plates separated by a distance of 0.24 m
As shown in the figure, an electron is fired with a speed of 3.59 × 106 m/s through a hole in one of the two parallel plates and into the region between the plates separated by a distance of 0.24 m. There is a magnetic field in the region between the plates and, as shown, it is directed into the plane of the page (perpendicular to the velocity of the electron). Determine the magnitude of the magnetic field so that...

The electron gun in a TV picture tube accelerates electrons between two parallel plates 1.20 cm apart with a 25.0 kV potential difference between them. The electrons enter through a small hole in the negative plate, accelerate, and then exit through a small hole in the positive plate. Assume that the holes are small enough not to affect the electric field or the potential. (a) What is the electric field between the plates? (b) What is the exit speed of...

A free electron is placed between two large, parallel, nonconducting plates that are horizontal and 7.83 cm apart. One plate has a uniform positive charge; the other has an equal amount of uniform negative charge. The force on the electron due to the electric field Upper E Overscript right-arrow EndScripts between the plates balances the gravitational force on the electron. What are (a) the magnitude of the surface charge density on the plates and (b) the direction of Upper E...

2. An Electron between two parallel plates has an initial velocity of 1.6*10°m/s. In between the plates is a uniform Electric Field which points down (see picture). The plates are separated by 1 em and they are each 2cm long. You can assume the electron begins halfway between the plates. a) Suppose that the electron just clears the top plate as it emerges from the plates. In this case, find the value of the electric field. b) Now that we...

An electron travels with speed 9.0×106 m/s between the two parallel charged plates shown in the figure. The plates are separated by 1.0 cm and are charged by a 200 V battery. (Figure 1) What magnetic field strength will allow the electron to pass between the plates without being deflected?

Finding the charge to mass (e/m) ratio of the electron Often in physics, we look for ways to find fundamental physical constants. From the set-up demonstrated in class, we are able to find a monumental combination of two physical constants-the charge of an electron (e) and the mass of an electron (m). Since the charge of an electron (e) is well known through other experiments, we will use the ratio of charge to mass to find the mass of an...

A small object with mass m, charge q, and initial speed v0 5.00x103 m/s is projected into a uniform electric field between two parallel metal plates of length 26.0 cm (Figure 1)
A small object with mass m, charge q, and initial speed v0 5.00x103 m/s is projected into a uniform electric field between two parallel metal plates of length 26.0 cm (Figure 1). The electric field between the plates is directed downward and has magnitude E 800 N/C. Assume that the field is zero outside the region between the plates. The separation between the plates is large enough for the object to pass between the plates without hitting the lower plate....
