Question

The e/m ratio of cathode rays is x unit, when hydrogen is filled in the discharge tube.
Options
A,x unit
B.$x/2$ unit
C.2x unit
D.$x/4$ unit

Answer 1

A cathode-ray tube (CRT) is a vacuum tube that creates a trace on a fluorescent film by deflecting an electron beam with applied electric or magnetic fields. An electric field accelerates electrons from one end of the tube to the other in a cathode ray tube. Owing to their speed, the electrons give up all of the energy they bear as they reach the tube's far end, and this energy is converted to other forms such as heat. X-rays are generated by converting a tiny volume of energy.

Complete answer:
A cathode-ray tube (CRT) is a vacuum tube that creates a trace on a fluorescent film by deflecting an electron beam with applied electric or magnetic fields. An electric field accelerates electrons from one end of the tube to the other in a cathode ray tube. Owing to their speed, the electrons give up all of the energy they bear as they reach the tube's far end, and this energy is converted to other forms such as heat. X-rays are generated by converting a tiny volume of energy.
We assume that rays were and are essentially negatively charged particles present or travelling about in a set of positively charged particles. This theory also aided scientists in their interpretation of atom structure. And he made the important discovery that the properties of cathode rays or electrons were independent of the electrode content or the composition of the gas contained in the cathode ray tube. Overall, we should deduce from all of this that electrons are the fundamental constituent of all atoms.
A small nucleus contains the majority of an atom's mass and much of its positive charge. The positively charged particle is known as a proton. The majority of an atom's volume is made up of free space.
The number of positively charged protons in the nucleus is equal to the number of electrons scattered outside the nucleus. This describes an atom's overall electrical neutrality.
Be it Hydrogen or deuterium, the properties of cathode rays or electrons were independent of the electrode content or the composition of the gas contained in the cathode ray tube.

So, option A is correct.

Note:
A small nucleus contains the majority of an atom's mass and much of its positive charge. The positively charged particle is known as a proton. The majority of an atom's volume is made up of free space.
The number of positively charged protons in the nucleus is equal to the number of electrons scattered outside the nucleus. This describes an atom's overall electrical neutrality.
