A charge moving ______ to the direction of the magnetic field does not experience any magnetic Lorentz force.
(A) parallel
(B) perpendicular
(C) antiparallel
(D) at any acute angle
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A) and (C) only
The magnetic Lorentz force is given by:
$\vec{F} = q \, (\vec{v} \times \vec{B})$
If $\vec{v}$ is parallel or antiparallel to $\vec{B}$, then $\vec{v} \times \vec{B} = 0$.
Answer: (A) parallel and (C) antiparallel
