At some instant the velocity components of an electron moving between two charged parallel plates are vx=2.0×105 m/s and vy=3.1×103 m/s. Suppose the electric field between the plates is uniform and given by E→=(120N/C)j. In unit-vector notation, what are (a) the electron’s acceleration in that field and (b) the electron’s velocity when its x coordinate has changed by 2.4 cm?

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...

An electron beam is passed through two charged parallel plates of length L = 20 cm and is seen to be deflected by a vertical distance d = 2.5 cm by the time it reaches the end of the plates. If the area between the plates is then filled with a uniform magnetic field B = 10-5 T pointing into the page, the electron beam is observed to be undeflected. What is the speed of the electrons? a) 1.41x106 m/s...

A uniform electric field exists in a region between two oppositely charged plates. An electron is released from rest at the surface of the negatively charged plate and strikes the surface of the opposite plate, 5.0 cm away, in a time 1.9 ✕ 10−8 s. (a) What is the speed of the electron as it strikes the second plate? (b) What is the magnitude of the electric field ?

The separation between two charged metallic plates is 15cm. The electric field between the plates is uniform and has an intensity of 3000N/C. An electron is released at rest at a point P precisely over the surface of the negative plate. A) In how much time will it reach the other plate? B) What is its velocity before reaching the plate? Thank you in advance!

A system designed to accelerate and deflect protons can be composed of two sets of charged parallel plates, the first with the plates aligned parallel to the y-axis and the second parallel to the x-axis. a. If the first section has a potential difference of 50 kV across its 6 mm gap what velocity (vx) will the proton achieve when it crosses the gap between the plates. (Hint: use kinetic energy) b. The proton then passes into center of the...

Two large conducting parallel plates A and B are separated by 2.4 m. A uniform field of 1500 V/m, in the positive x-direction, is produced by charges on the plates. The center plane at x = 0.00 m is an equipotential surface on which V = 0. An electron is projected from x = 0.00 m, with an initial velocity of 1.0 × 107 m/s perpendicular to the plates in the positive x-direction, as shown in the figure. What is...

Two parallel plates are charged such that there is a 400V potential difference between them. A proton is fired from a point midway between the plates toward the positive plate. The protons initial speed is 1.5 × 105 m/s. a) Show that this speed is insufficient for the proton to reach the positive plate. b) What is the proton’s speed as it collides with the negative plate? Possibly useful information: mass of a proton = 1.67 × 10−27 kg, charge...

In the figure, an electron accelerated from rest through potential difference V1=1.39 kV enters the gap between two parallel plates having separation d = 22.1 mm and potential difference V2= 98.7 V. The lower plate is at the lower potential. Neglect fringing and assume that the electron's velocity vector is perpendicular to the electric field vector between the plates. In unit-vector notation, what uniform magnetic field allows the electron to travel in a straight line in the gap?
