Answer:
we are given that alpha particles (+ve charge) moving along the direction of +x axis and
the force experienced due to magnetic field is in the direction of +Y axis.
since the force is vector product and it is given by 
, magnetic field should be in the direction
, magnetic field should be in the direction of -z axis as shown in figure using axis of cartesian coordinate system and
also by right-hand screw rule for cross product of vectors
