Four charges A, B, C, D are shown here, moving with equal speeds in a uniform magnetic field. Which charge experiences the maximum force?
Correct answer: C. C
- A. A
- B. B
- C. C
- D. D
Explanation
As we know F = qvB sin θ. Where θ is the angle between the velocity and the magnetic field, a greater angle leads to maximum force. In the given charges, the angle is greater in the case of C, between the magnetic field and velocity. Therefore, Charge C experiences the maximum force.

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.
