A charged particle is released from rest in a region of a uniform magnetic field along the direction of the magnetic field. The path of the charged particle in the magnetic field will be
- A straight line
- B helical
- C circular
- D elliptical
Answer & Solution
Correct Answer
(A) straight line
Step-by-step Solution
Detailed explanation
\( \vec{F} = q(\vec{v} \times \vec{B}) \) \( \vec{v} = 0 \) \( \vec{F} = q(0 \times \vec{B}) = 0 \) The particle remains at rest, hence its path is a straight line.
