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.
