The constancy of e/m ratio for electron shows that
Answers
Answer:
Electrons are universal particles of all matter
Answer:
The electron mass ratio ( e/m remains constant, demonstrating that electrons are a universal component of matter.
Explanation:
•British physicist J.J. Thomson used a specially made cathode ray tube to measure the cathode ray particle's electrical charge (e) to mass (m) ratio.
•Thomson connected the experiment to cathode rays and various intensities and energies of electric or magnetic fields. He was able to calculate the value of e/m, or the ratio of charge to mass of cathode ray particle, as e/m=1.7588201011 Ckg-1.
•Here, e denotes the particle's charge in coulombs and m its mass in kilogrammes (C). The cathode ray particle, subsequently known as the electron, has a negative charge, and since the particles have this charge, it is symbolised by the symbol e. Regardless of the gas's composition, the value of e/m remained constant.
•Even though the gas in the discharge tube or the cathode material may vary, the electron mass ratio remains constant, demonstrating that electrons are a universal component of matter.
