A strong magnetic field is applied on a stationary electron :
- A The electron moves in the direction of the field
- B The electron moves in an opposite direction
- C The electron remains stationary
- D The electron starts spinning
Answer & Solution
Correct Answer
(C) The electron remains stationary
Step-by-step Solution
Detailed explanation
The magnetic force on a charged particle is given by the formula \(\vec{F}=q(\vec{v} \times \vec{B})\). Since the electron is stationary, its velocity \((v)\) is zero, making the net magnetic force zero. Therefore, the electron experiences no push or pull and remains at rest. C)…
