The region between y = 0 and y = d contains a magnetic field

\overrightarrow B = B\widehat z

. A particle of mass m and charge q enters the region with a velocity

\overrightarrow v = v\widehat i.

If d

=

{{mv} \over {2qB}},

the acceleration of the charged particle at the point of its emergence at the other side is :
