Why does the charge to mass ratio of positive rays depends on the gas taken in the discharge tube whereas charge to mass ratio of cathode rays is same for all gases?
The charge-to-mass ratio for the positively charged canal rays depends on the gas used to fill the tube because the nature of the ions produced when the atoms or molecules lose electrons depends on the identity of the gas.
What will be the ratio to charge of electron and mass?
Hence, deflection is not dependent on just the charge and mass as long as we maintain the charge to mass ratio. 2….What is an Electron?
| Mass of Electron | m = mass of electron in kg = 9.10938356 × 10-31 kilograms. |
|---|---|
| Charge of Electron | e = magnitude of the charge of the electron in coulombs = 1.602 10-19 coulombs. |
Why does the charge to mass ratio of anode rays depend on the gas from which it originates?
Anode rays are produced in the discharged tubeon applying a high electrical voltage to the gas which is present in the tube. The different gases have different types of positive rays,that contain particles of different mass and charge. Therefore, the charge to mass ratio of anode depends on the gas.
Why is the charge mass e/m ratio variable for anode rays but constant for cathode rays?
Originally Answered: Why is the charge/mass (e/m) ratio variable for anode rays but constant for cathode rays? Cathode rays are always made up of same particle that is electrons , hence e/m ratio remains same. Anode Ray are made up of kernels , which is different in different case . Hence e/m ratio different .
Why do we need to charge mass ratio?
Significance. In some experiments, the charge-to-mass ratio is the only quantity that can be measured directly. Often, the charge can be inferred from theoretical considerations, so that the charge-to-mass ratio provides a way to calculate the mass of a particle.
Why do electrons have charge?
I can’t really answer this question, but based on experiments carried out by scientists, electrons have a negative charge because they are attracted to anodes (a positively charged electrode). We know that opposite charges attract. Electrons are known as fundamental particles. Electron does not acquire charge.
Why is electron negatively charged?
Electric charge is a physical property of matter. It is created by an imbalance in a substance’s number of protons and electrons. The matter is positively charged if it contains more protons than electrons, and it is negatively charged if it contains more electrons than protons.
Why does e M ratio of negatively charged particles remain constant for all gases?
Why does e/m ratio of negatively charged particles remain constant for all gases? The mass and charge of an electron is same irrespective of the substance (element or compound) it is generated. Hence, e/m or chargeto mass ratio is constant and independent of the type of gas.
