A charged particle of mass m and charge q moves with a constant velocity  v = a i along the positive x-direction. It enters a region of magnetic field which is directed towards positive z-direction, from x = l, which is given by B = b k and moves in a circular path.

Which is the true statement regarding the frequency of the rotation?

depends on the value of b

Frequency : \(\omega \) = \(\frac{qB}{m}\)
