Question

True or False
Cathode rays deflect towards positive plate in the presence of electric field.

Answer 1

Cathode rays consist of negatively charged particles. When cathode rays are subjected to an electrical field, these get deflected towards the positively charge plate i.e. Anode. We know that a positively charged body would attract only a negatively charged body, therefore the particles of cathode rays carry negative charge. Cathode rays also get deflected when these are subjected to a strong magnetic field. The electrons in the cathode rays would deflect toward the positively charged plates, and away from the negatively charged plates.
