Moving Charges and Magnetism

Question:

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:

Options:

(A) and (B) only

(B) and (D) only

(A) and (C) only

(A) and (D) only

Correct Answer:

(A) and (C) only

Explanation:

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
