The voltage applied across X-plates deflects the beam:
Correct answer: B. Horizontally on the screen
- A. Vertically or the screen
- B. Horizontally on the screen
- C. Both (a) and (b)
- D. None of these
Explanation
The voltage applied across the X-plate (horizontal deflecting plates) deflects the electron beam horizontally on the screen of the Cathode Ray Oscilloscope (CRO). By controlling the voltage applied to the X-plates, the horizontal position of the electron beam can be adjusted, allowing the display of the waveform's time or frequency.

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.
