MCQ
Cathode rays are deflected by:
- ✓electric and magnetic fields
- Bmagnetic field only
- Cthin metal foils only
- Delectric field only
✓
Answer
Correct option: A.
electric and magnetic fields
(a) electric and magnetic fields
Explanation: When an electric field is applied to a stream of cathode rays, they get deflected towards the positive plate. On the application of a magnetic field perpendicular to the path of the cathode rays, they get deflected in the direction expected of negative particles.
