Question
Carefully study Figure 29.4 and 29.5 to get familiar with the Right hand rule for the cross product of vector. A. Zero 8. Upward. CDownward. D. North when a positive charge is moving north, and the B field is pointing toward north, the magnetic force will be when a positive charge is moving sorth, and the B field is pointing toward north, the magnetic force will be When a positive charge is moving east and the B field is pointing toward north, the magnetic force will be When a negative charge is moving east and the B field is pointing toward north, the magnetic force will be When a positive charge is moving west and the B field is pointing toward north, the magnetic force will be When a negative charge is moving west and the B field is pointing toward north, the magnetic force will be E. South F. NortheastExplanation / Answer
We simply use the right palm rule to determine the direction:
The right hand rule states that, to find the direction of the magnetic force on a positive moving charge, the thumb of the right hand point in the direction of v, the fingers in the direction of B, and the force (F) is directed perpendicular to the right hand palm.
The direction of the force F on a negative charge is in the opposite sense to that above (so pointed away from the back of your hand).
