Dear Student,

Pitch of the helical path is distance between two consecutive points along magnetic field direction. It is given by,

$p i t c h = (v \cos θ) T$

Where, T = time period of the charged particle

$T = \frac{2 π m}{q B}$

v = velocity of the charged particle

m = mass of the charged particle

B = magnetic field
