If we double the applied magnetic field, the e/m of an electron will be:
Correct answer: B. Remain same
- A. Half
- B. Remain same
- C. Double
- D. Zero
Explanation
Charge-to-mass ratio (e/m) of electron is fundamental constant property of particle itself. It does not depend on external conditions like strength of applied magnetic field.

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.
