Question

A charge of +10 µC enters a uniform magnetic field parallel to its direction. What will happen to the charge?

• A. Perform circular motion in a plane perpendicular to the field.
• B. Perform circular motion in a plane parallel to the field.
• C. Continue to move with acceleration
• D. Move undeviated with constant velocity.

Answer 1

The correct option is D

Move undeviated with constant velocity.

As the magnetic field is parallel to the charge, no magnetic Lorentz force will act on it and it will move undeviated with constant velocity.
