Problem

A charged particle moving along the positive

x

-direction with velocity

v

enters a region from

x=0

x=d

having a uniform magnetic field

\mathbf{B}=-B\hat{\mathbf{k}}

. The particle is deflected through an angle

\theta

from its initial path. The specific charge of the particle is: (a)

\dfrac{Bd}{v\cos\theta}

(b)

\dfrac{v\tan\theta}{Bd}

(c)

\dfrac{v\sin\theta}{Bd}

(d)

\dfrac{B\sin\theta}{vd}
