The potential difference between the accelerating plates of a TV set is about 20 kV. If the distance between the plates is 1.0 cm, find the magnitude of the uniform electric field in the region between the plates.  N/C

Suppose that a wire leads into another, thinner wire of the same material that has only half the cross-sectional area. In the steady state, the number of electrons per second flowing through the thick wire must be equal to the number of electrons per second flowing through the thin wire. If the electric field Ej in the thick wire is 4.3 x 102 N/C, what is the electric field E2 in the thinner wire? i N/C

Electric Fields 12 v.C What is the direction of the electric field E2? Enter the numerical value in units of y degrees above the +x axis. E2 Type your answer... E2y 13 If electric field E1 has a magnitude of E1 = 3.7 N/C, what is the magnitude of the total (or net) electric field? Enter the numerical value in SI units. E1 E2x Type your answer.. Two electric fields (E1 and E2) occupy the same point in empty space, as shown above. Electric field E2 has a magnitude of E2 = 5.0 N/C, an x-component of E2x = 3.0 N/C, and a y-component of E2y = 4.0 N/C. %3D %3D

A particle (m = 70 mg, q = -5.0 µC) %3D moves in a uniform electric field of 60 kN/C in the positive x-direction. At t = 0, the particle is moving 30 m/s in the positive x-direction and is passing through the origin. Determine the maximum distance beyond x = 0 the particle travels in the positive x- direction. Select one: A. 315.0 m B. 210.0 m C. 52.5 m D. 105.0 m

Part A -23 kg) is accelerated through AKt ion (mass of 6.5x10 a cell membrane at 2.3 x 106 m/s². What is the electric field between the membrane walls? 9340 N/C 49 N/C 4.9 N/C 934 N/C Submit Request Answer

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.
