In a cathode-ray tube (CRT), an electron travels in a vacuum and enters a region between two "deflection" plates which have equal and opposite charges. The dimensions of each plate are L = 11 cm by d = 4 cm, and the gap between them ish = 2.5 mm. (Note: the diagram is not drawn to scale and the direction of the electric field may not be correct, depending on your randomization.) L During a 0.001 s interval while it is between the plates, the change of the momentum of the electron A p is kg m/s. Part 1 Your answer is correct. What is the electric field between the plates?What is the electric field between the plates? E = N/C Attempts: 4 of 10 used Part 2 * Your answer is incorrect. What is the charge (both magnitude and sign) of the upper plate? q = 2.458e-8 Save for Later Attempts: 1 of 10 used Submit
