A charged particle entered in a magnetic field anti-parallel to the field, magnetic force on this particle is:
- A
BINA
- B
BeVsinθ
- C
Zero
- D
Iqtv
The magnetic force acting on the charged particle is given by :
F=qvBsinθ ……………..(1)
Where,
q is charged particle
v is the speed of the charged particle
θ is the angle between velocity and magnetic field
When a charged particle enters the uniform magnetic field anti-parallel to it, then the angle between the electron and magnetic field is 0 degrees. So,
sin(θ) = sin (0) = 0
Putting in eq. (1) we get:
⇒ F = qv B sin (0) = qvB(0) = 0
So, F = 0
Hence, no force will act on the charged particle.

This option is incorrect.
This option is incorrect.
If the particle velocity happens to be aligned parallel to the magnetic field or is zero, the magnetic force will be zero.
This option is incorrect.
