By measuring the deflection of cathode rays in electrical and magnetic fields J.J. Thomson was able to determine what?

J.J. Thomson was able to determine the charge-to-mass ratio of an electron by measuring the deflection of cathode rays in electrical and magnetic fields. This discovery led to the identification of electrons as fundamental particles in atoms.


Charge to mass ratio of electron?

The charge to mass ratio of an electron is approximately -1.76 x 10^11 coulombs per kilogram. This means that electrons have a very small mass compared to their charge. This value was first measured by J.J. Thomson in his experiments with cathode rays.


What was John Thomson's experiment for the modern model?

John Thomson's experiment involved studying the properties of cathode rays in a cathode ray tube. By observing the behavior of these rays in the presence of electric and magnetic fields, Thomson was able to determine the charge-to-mass ratio of the electron. This experiment provided important evidence for the existence of subatomic particles and laid the groundwork for the development of the modern atomic model.


What is The ratio of the specific charge of an electron to that of a positron is?

The ratio of the specific charge of an electron to that of a positron is 1:1. Both the electron and positron have the same magnitude of charge but opposite in sign, with the electron being negative and the positron being positive.


Who determined the charge to mass ratio to the positive rays?

J.J. Thomson determined the charge-to-mass ratio of positive rays in his experiments with cathode rays, which led him to discover the existence of electrons. This work was instrumental in validating the existence of subatomic particles and laying the groundwork for modern atomic theory.

What famous experiment did J.J thomas conduct?

J.J. Thomson is famous for his experiments that led to the discovery of the electron in 1897, which revolutionized our understanding of atomic structure. His work with cathode rays in a vacuum tube allowed him to determine the charge-to-mass ratio of the electron.


When J J Thomson discovered the electron what physical property of the electron did he measure?

Thomson measured the charge-to-mass ratio of the electron, which was found to be much smaller than that of any known atom. This suggested that the electron was a fundamental particle and not a substructure of an atom.


What device did J. J. Thomson use to detect electrons and measure their properties?

J. J. Thomson used a cathode ray tube to detect electrons and measure their properties. By studying the behavior of electrons in the tube, he was able to determine their charge-to-mass ratio, leading to the discovery of the electron.


What experiment did j.j Thomson do?

J.J. Thomson is best known for his experiment with cathode rays, where he deduced the existence of negatively charged particles (electrons) in atoms. By measuring the deflection of these rays in a magnetic field, Thomson was able to determine the charge-to-mass ratio of the electron.

What is a Cathode ray gun?

basically JJ Thomson wanted to find out what a cathode ray was made of. Cathode tubes are a tube with wires in them. Scientists discovered that if the created a vacuum in the tube and sent a charge through the wires, it glowed. JJ Thomson set up a cathode ray and placed magnets on either side. This deflected the ray so the tube didn't glow. This meant the rays were negatively charged which meant they were made of negatively charged particles or electrons.


In the electron charge to mass experiment if the electron is replaced by a proton or neutron would the charge to mass ratio value still be the same why or why not?

No, the charge to mass ratio value would not be the same if the electron is replaced by a proton or neutron. Protons and neutrons have different charge and mass compared to electrons, so the ratio would vary. The charge to mass ratio is specific to each type of particle.


What is an alternative method to measure the charge to mass ratio of an electron?

Modern Mass Spectrometry is the alternative method to measure the charge to mass ratio of an electron.
