The function of grid in cathode ray oscilloscope is:
Correct answer: C. Both (a) and (b)
- A. To control the number of electrons accelerated by anode
- B. To control trilaterals of spot formed on the screen
- C. Both (a) and (b)
- D. None of these
Explanation
While the grid does control the intensity of the electron beam and influences the number of electrons reaching the screen, its primary role is in controlling the deflection and focusing of the beam rather than directly regulating the number of electrons accelerated by the anode.

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.
