An electron is moving along the line of force in magnetic field B with velocity u, then the maximum force acting on the charge is given by _.
Correct answer: D. Zero
- A. Bue
- B. Bq/u
- C. Bu/q
- D. Zero
Explanation
In case above the magnetic field and velocity are parallel , so angle between them will be zero if put it in equation for the force F=qVBsin Answer will be zero , hence there will be zero force acting on the charge

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.
