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 = 5 cm, and the gap between them is h = 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.) What is the charge (both magnitude and sign) of the upper plate? During a 0.001 s interval while it is between the plates, the change of the momentum of the electron Ap is < 0, -1.20e-16, 0 > kg m/s. What is the electric field between the plates? Hint: remember the Momentum Principle (the relationship between Impulse and change in momentum.) N/C 9= Additional Materials eBook L С Ē
