Question

what are the cathode rays? what is the nature of charge on cathode rays?​

Answer 1

Answer:

Cathode rays consist of negatively charged particles called electrons. So the nature of charge possessed by particles of cathode rays is negative.

These rays were then termed as negatively charged rays or cathode rays because of the fact that they were moving away from the cathode and going toward the anode which is the positively charged plate.
