An electron is projected in a uniform magnetic field along the direction of field, the electron will experience: |
a force opposite to the magnetic field a force in the direction of magnetic field no force in magnetic field a force perpendicular to the magnetic field |
no force in magnetic field |
The correct answer is Option (3) → no force in magnetic field The force on a charged particle in magnetic field is, $F=q(v×B)$ As v is parallel (or anti-parallel) to B, $(v×B)=0$ $⇒F=q(v×B)$ $=0$ |
