MHT CET · Physics · Magnetic Effects of Current
A charged particle is always moving parallel to the direction of magnetic field. The
magnetic force acting on the particle will be
- A opposite to its velocity.
- B zero.
- C perpendicular to its velocity.
- D along its velocity.
Answer & Solution
Correct Answer
(B) zero.
Step-by-step Solution
Detailed explanation
(C)
Magnetic force is given by \(\mathrm{F}=\mathrm{qvB} \sin \theta\)
If \(\theta=0^{\circ}\), then \(\mathrm{F}=0\)
Magnetic force is given by \(\mathrm{F}=\mathrm{qvB} \sin \theta\)
