Lec 02 Discovery of Fundamental ParticlesProperties of Cathods Rays, 11th Chemistry

Thomson's analysis of cathode ray experiment led him to conclude that electrons were fundamental particles. e//m ratio for particles in cathode rays was found to be independent of the nature of the gas taken in the tube.

Which one of the three fundamental particles is present in the cathode rays ?

Assertion (A), study of discharge of electricity through gases at low pressure resulted in the discovery of cathod rays . Reason (R ): cathod rays are deflected by both magnetic and electric fields and the direction of deflection shows that they are nagatievly charged .
