A charged droplet is released between 2 vertical plates with an electric field across them. Calculate the deflection (z) of the droplet by the time it leaves the electric field region. You should first calculate the time spent by the droplet accelerating under the action of gravity Droplet mass: 3.5x10-15 kg Droplet charge: 861x10-19 C Gap (d): 0.1 m Length of plates (L): 0.3 m Voltage (VA-VB): 5 V Acceleration due to gravity 9.8 ms-2
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 = 12 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.) During a 0.001 s interval while it is between the plates, the change of the momentum of the electron ΔP is < 0, 9.60e-17, 0 > kg m/s.What is the electric field between the plates?
