A charge moving with velocity v in X - direction is subjected to a field of magnetic induction in the negative X direction. As a result the charge will

$F=q(\vec{V}\times \vec{B})$
$=qVBsin0$
$=qVBsin(180^0)$       $(\because \text{ velocity is in X-direction and B is in -X-direction})$
$=0$                      $(\because sin180^0=0)$
So, charge will be more unaffected.
