A cathode ray tube (CRT) is used to display images in some televisions and computer monitors by accelerating electrons from the cathode toward the anode, which is at a higher potential than the cathode. If the potential difference between the cathode and anode is 25 kV, at what speed do the electrons move as they reach the anode? Express your answer in scientific notation. (in m/s) (Hint: energy is conserved)

Older televisions display a picture using a device called a cathode ray tube, where electrons are emitted at high speed and collide with a phosphorescent surface, causing light to be emitted. The paths of the electrons are altered by magnetic fields. Consider one such electron that is emitted with an initial velocity of 1.85 107 m/s in the horizontal direction when magnetic forces deflect the electron with a vertically upward acceleration of 5.45 1015 m/s2. The phosphorescent screen is a...

A cathode ray tube (CRT) is used to accelerate electrons in some televisions, computer monitors, oscilloscopes, and x- ray tubes. Electrons from a heated filament pass through a hole in the cathode; they are then accelerated by an electric field between the cathode and the anode (see the figure below). + Assist Che ry View Show Guid rcal deflertion Print Ques Repa te) 1 out of 3 attempts Atter the electrons pass through the anode, they are...
