Whether the cathode ray particles have positive or negative charge can be determined by ?
Answer: Passing them through oppositely charged plates
Explanation
The charge of cathode ray particles can be determined by passing them through oppositely charged plates.
Cathode rays are composed of negatively charged particles called electrons.
When these rays pass through an electric field with oppositely charged plates
They are deflected towards the positively charged plate, demonstrating their negative charge.
