If the particle enters a magnetic field at a certain angle, then what will be the pitch of the path be given by?
Answer & explanation
Correct answer: option 1
Pitch of the Helical Path: The distance travelled in one time period along the axis of the helical path is called the pitch of the path. Therefore,
theta}{qB}$
$ Pitch = vcos\theta T = vcos\theta \times \frac{2\pi m}{qB} = \frac{2\pi m v cos\theta}{qB}$
