Question
A charged particle moves at a velocity v in a uniform magnetic field B. The magnetic force experienced by the particle is maximum
- Always constant
- If B and v are perpendicular to each other
- If B and v are parallel
- Always zero
Hint:
Magnetic force acting on the charged particle F=q(v×B)=qvB sinθ
The correct answer is: Always constant
Magnetic force acting on the charged particle F=q(v×B)=qvB sinθ
If θ=90 degree ⟹ sin90=1
⟹ F=maximum
Thus, magnetic force is maximum If B and v are perpendicular to each other
If θ=90 degree ⟹ sin90=1
⟹ F=maximum
Thus, magnetic force is maximum If B and v are perpendicular to each other
