A charge of 2C is travelling parallel to a magnetic field of 4T with 20 m/s. Calculate the net force on it.
Correct answer: C. 0N
- A. 160N
- B. 120N
- C. 0N
- D. 100N
Explanation
q = 2 C B = 4 T v = 20 m/s F = q ( v × B ) As , q is parallel to B , so , net force acting on charge is 0 N .

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.
