Answer:

As per right hand rule the force direction magnetic field is along - z axis

Explanation:

As we know that the force on the moving charge due to magnetic field is given as

[tex]\vec F = q(\vec v \times \vec B)[/tex]

here we know that

[tex]\vec v = v\hat i[/tex]

[tex]q = - e[/tex]

[tex]\vec F = F (-\hat j)[/tex]

so we will have

[tex]F(-\hat j) = (-e)(v (\hat i) \times \vec B)[/tex]

so direction of magnetic field must be along -Z Axis
