When strong magnetic field is applied on a stationary electron, the electron:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → remains stationary.
When a strong magnetic field is applied to a stationary electron, the electron remains stationary because the magnetic force on the electron is zero.
Lorentz force, $F=q(v×B)$
$=q(0×B)$ [$v=0$ (stationary)]
$=0$
