FAQ
Q: What is the purpose of using electric fields in accelerating and deflecting electrons in a cathode ray tube?
A: Electric fields are used to accelerate and deflect electrons in a cathode ray tube to control the motion and position of the electron beam on the screen.
Q: How are electrons accelerated in an electron gun within a cathode ray tube?
A: Electrons are accelerated in an electron gun by applying a voltage difference between the cathode and anode, creating an electric field that accelerates the electrons towards the anode.
Q: How are electrons deflected in a cathode ray tube using electric fields?
A: Electrons are deflected in a cathode ray tube using electric fields between two plates, which exert a force on the electrons and allow for precise control over the position of the electron beam on the screen.
Q: What is the formula used to calculate the strength of the electric field between deflection plates?
A: The strength of the electric field between deflection plates can be calculated using the formula E = F/q, where E is the electric field strength, F is the force experienced by the electron, and q is the charge of the electron.
