Question

A cathode-nay tube (CRT) is an evacuated glass tube. Flectrons are produced at one end, usually: by the heating of a metal. Afer being focused electrornagnetically into a beam, they are aecelerated through a potential difference, called the accelerating potential. The electrons then strike a coated sereen, where they transfer the ir coergy so the ceating through collisions, causing it to glow. CRTy are found in ascillospopes and coatpuler monitors, as well as in earlier versions of television screens. If the accelerating potential is 95.0 V, whan is the change in the electric potential energy of the electrons when they accelerated through the potential?.

Answer 1

A cathode-ray tube (CRT) is an evacuated glass tube that contains electrodes and a rarefied gas. When a high voltage, known as the accelerating potential, is applied to the electrodes, electrons are emitted from the cathode and accelerated toward the anode. These accelerated electrons then strike a phosphor-coated screen at the end of the tube, causing it to glow.

Step-by-step explanation:

A cathode-ray tube (CRT) is an evacuated glass tube that contains electrodes and a rarefied gas. When a high voltage, known as the accelerating potential, is applied to the electrodes, electrons are emitted from the cathode and accelerated toward the anode. These accelerated electrons then strike a phosphor-coated screen at the end of the tube, causing it to glow. The change in the electric potential energy of the electrons can be calculated using the formula ΔPE = q×V where ΔPE is the change in electric potential energy, q is the charge of the electron, and V is the accelerating potential. In this case, since the accelerating potential is given as 95.0 V, the change in the electric potential energy of the electrons when they are accelerated through this potential is 95.0 times the charge of an electron.
