CRO works by deflecting the beam of electron as they pass through:
Correct answer: B. Uniform electric field between two sets of parallel plates
- A. Uniform magnetic field
- B. Uniform electric field between two sets of parallel plates
- C. Non-uniform magnetic field
- D. None of these
Explanation
This is the correct option. A CRO works by deflecting a beam of electrons as they pass through a non-uniform magnetic field. By varying the strength and direction of this magnetic field, the electron beam can be precisely controlled to trace out a desired waveform on a fluorescent screen, allowing for the visualization of electrical signals.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
