Question

Complete the given statement. a magnetic field exerts a force on a charged particle:

• A. that is perpendicular to both the magnetic field and the particle's direction of travel.
• B. that is parallel to both the magnetic field and the particle's direction of travel.
• C. that is in the same direction as the particle's direction of travel.
• D. that is in the same direction as the magnetic field.
• E. that is perpendicular to the magnetic field only.

Answer 1

The correct option is A that is perpendicular to both the magnetic field and the particle's direction of travel.

Magnetic force $\overrightarrow{F}=q(\overrightarrow{v}\times \overrightarrow{B})$

As $(\overrightarrow{v}\times \overrightarrow{B})$ points in the direction perpendicular to both $\overrightarrow{v}$ and $\overrightarrow{B}$

$⟹$ $\overrightarrow{F}\perp$ $\overrightarrow{v}$ as well as $\overrightarrow{B}$.
