If a charged particle enters a region where electric and magnetic fields are parallel to its motion, it will:
Correct answer: C. Speed up
- A. Deflect upwards
- B. Deflect downwards
- C. Speed up
- D. Speed down
Explanation
Option C is correct since the magnetic and electric fields are parallel to each other so the charge will speed up.

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.
