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.
