In a television picture tube (CRT), electrons are accelerated by thousands of volts through a vacuum. If a television set is laid on its back, would electrons be able to move upward against the force of gravity? Find the potential difference, acting over a distance of 3.5 cm, that would be needed to balance the downward force of gravity so that an electron would remain stationary. Assume that the electric field is uniform. [Electron mass : 9.11 x 10-31 kg]

In a television picture tube, electrons strike the screen after being accelerated from rest through a potential difference of 24 600 V. The speeds of the electrons are quite large, and for acourate calculations of the speeds, the effects of special relativity must be taken into account. Ignoring such effects, find the electron speed just before the electron strikes the screen. Select Tutal
The electrons that produce the picture in a TV set are accelerated by a very large electric force as they pass through a small region in the neck of the picture tube
The electrons that produce the picture in a TV set are accelerated by a very large electric force as they pass through a small region in the neck of the picture tube. This region is 1.4 cm in length, and the electrons enter with a speed of 1× 105 m/s and leave with a speed of 1.5 × 108 m/s. a. What is their acceleration over this 1.4 cm length? Answer in units of m/s2. b. How long is the...

Part B please?
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...
