Particles of the cathode rays are fundamental to all matter.
Matter contains negative charge and by inference positive charge.
There are subatomic size particles in an atom.
Cathode rays have mass.
Explanation:
<u>Radiation emitted from cathode was accelerated toward the anode in tubes.</u>
This means that the cathode rays which are travelling towards anode (positively charged) are negatively charged. Atom was considered to have subatomic particles.
C and D are correct.
<u>Cathode rays was observed to be same regardless of composition of cathode.</u>
This means that particles of cathode rays are fundamental to all the matter.
A is correct.
<u>The rays are influenced by the magnetic and electric field and also they move a light fan when placed inside the tube. </u>
