Answer:
Case A: - x axis
Case B: - x axis
Case C: no force as the direction of v and B are parallel.
Explanation:
Solution:
- The direction of Force exerted by the magnetic field B with a moving charge q with a velocity of v is given by an expression:
                   F = q*(v x B)
- Where F: force vector exerted by the field
       v: velocity vector of charged particle q.
       B: magnetic field direction
- The cross product of v with B:
    We will use right hand rule in which our fingers curl from v to B, the direction of the thumb denotes the direction of applied force. Hence,
                Case A: - x axis
                Case B: - x axis
                Case C: no force as the direction of v and B are parallel.
