- An evacuated tube uses an accelerating voltage of 55 kV to accelerate electrons to hit a copper plate and produce X-rays. Non-relativistically, what would be the maximum speed of these electrons before hitting the copper plate? Hint Maximum speed of the electrons is m/s. (Use the "E" notation to enter your answer. For example, to enter 3.14 x 10¹2, type in "3.14E12".) Question Help: Message instructor Submit QuestionPlz correct solutionA pair of parallel plates are separated by a distance of 1 cm and are connected to a 12V battery. The magnitude of the electric field between the two plates is |E1|. A second pair of parallel plates that are identical to the first is separated by a distance of 2 cm and is connected to a 4V battery. The magnitude of the electric field between these two plates is |E2| which of the following describes |E2| in terms of |E1|? a) |E2| = 6|E1| b) |E2| = 8|E1| c) |E2| = 2/7 |E1| d) |E2| = 1/6 |E1|

If the charge velocity at t = 0 is v(0) = (2ax + 4ay +3az) × 105 m/s: %3D give the unit vector showing the direction in which the charge is accelerating at t = 0. find the kinetic energy of the charge at t = 0. Answers: a. Blank 1ax + Blank 2ay + Blank 3 az b. Blank 4 fJA proton is moving under the combined influence of an electric field (E = 2569 V/m) and a magnetic field (B = 2.45 T), as shown in the figure. Assuming the proton is moving in the direction shown in the figure with speed 255 m/s at the instant it enters the crossed fields, what is the acceleration of the proton? (units are in m/s^2)Your object has mass 34.4 kg, and you ve separated the boxes of protons and electrons by a distance of 77 m. If you were to release the clump of protons from their box, how much acceleration would the clump of protons undergo due to its attraction to the clump of electrons in the other box? 9.56E+23 m/s^2 1.20E+23 m/s^2 2.39E+23 m/s^2 4.78E+23 m/s^2
