An electron moving in the horizontal direction passes through the plates of a capacitor that has a width of 3.0cm and develops a vertical electric field of 5.0x10^6 N/C in the upward direction. What is the speed and the direction of the electron with respect to the horizontal as it emerges from the other side of the capacitor?

An electron, initially at rest, is accelerated through a potential difference of 285 V. It then passes midway between two parallel plates providing a uniform electric field perpendicular to the direction in which it is travelling. The plates are 50 mm long and 25 mm apart and there is a potential difference of 71 V between them. Find (a) The speed of the electron after its initial acceleration and (b) The transverse deflection experienced by the electron as it emerges...

The figure below shows an electron passing between two charged metal plates that create an 85 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 2.60×106 m/s, and the horizontal distance it travels in the uniform field is 4.30 cm. What is its vertical deflection? What is the vertical component of its final velocity? At what angle...

The direction of the magnetic force on an electron moving through a magnetic field is the same as the direction of the vector formed by taking the cross product of the velocity with the magnetic field (v x B).            True/ False The magnetic field is also referred to as the magnetic flux _____________ [one word]. Consider a particle moving through a magnetic field. If the magnetic field doubles and the velocity of the particle halves, the magnetic force will:...

In the figure, an electron is projected horizontally midway between two parallel plates that are separated by 7.75 dm. The electrical field due to the plates has magnitude 517,000 MN/uC between the plates away from the edges. If the plates are 7.30 hm long, find the minimum speed of the electron if it just misses one of the plates as it emerges from the field (which plate will the electron miss?). (e = 1.60 × 10-19 C, ε0 = 8.85...

Two oppisitely charged horizontal plates are seperated by a distance d=2cm and each has a length L=5cm. The electric field between the plates a uniform and has a magnitude of E=115N/m. An electron is projected between the plates with a horizontal initial speed of v0 =103m/s as shown.Assuming this experiment is conducted in a vacuum, where will the electron strike the upper plate?

A beam of electrons is shot from left to right (+x direction) at a speed of 3 x 105 m/s through a pair of plates that are 3 cm apart and are uniformly charged. They produce a force of 4.8 x 10–17 N upward on the electron (+y direction).   So that our results are unambiguous, vectors pointing from left to right will be called +x, and from bottom to top (along the surface of the paper) will be +y.   Vectors...
