Use the diagram above for the directions of the various axes.
Positive Charge, Velocity: -x, B-Field: ???, Force: +y
Positive Charge, Velocity: -z, B-Field: +y, Force: ???
Negative Charge, Velocity: ???, B-Field: +y, Force: -z
Explanation / Answer
Forces is qv X B
using Right hand rule,
i) B-field is +z
II). force is +x
III). velocity is -x : charge is negative
