Question:
When an electron is kept in a strong magnetic field, then
When an electron is kept in a strong magnetic field, then
Show Hint
The magnetic force on a charge depends on its velocity. A charge at rest feels no magnetic force.

- electron moves in opposite direction of applied magnetic field.
- electron moves in the direction of applied magnetic field.
- electron moves in the direction of perpendicular direction of magnetic field.
- electron remains stationary at the same position.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
The magnetic force on a charge is \(\vec{F}=q(\vec{v}\times\vec{B})\).
Step 2: Electron at Rest
The electron is kept in the field, so \(v=0\).
Step 3: Result
\(\vec{F}=0\). With no force, the electron has no reason to move.
Final Answer:
The electron stays at rest at the same position. \[ \boxed{\text{(D) }\text{electron remains stationary at the same position}} \]
