The electron gun in a televeision tube is used to accelerate electrons (mass of 9.10939 x 10^-31 kg and charge of -1.60218 x 10^-19 C) from rest to 2 x 10^7 m/s within a distance of .053 m. What electric field is required?
An electric field is a physical field produced by electrically charged particles that affects the behavior of other charged particles in its vicinity.
The electric field is responsible for accelerating electrons towards the screen of a television tube, resulting in the formation of an image.
The strength of the electric field is determined by the voltage applied to the tube and the distance between the cathode and anode plates.
If the electric field is too weak, the electrons will not be accelerated enough to reach the screen of the television tube, resulting in a dim or distorted image.
Yes, the electric field can be adjusted by changing the voltage and distance between the cathode and anode plates, which can alter the acceleration of electrons and therefore change the image displayed on the screen.
