its b on edge \(-u-)/

Answer:

By right hand rule direction of force will be towards left

Explanation:

Here we know that force due to magnetic field on moving charge is given by

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

here as we can see the figure

v = velocity of charge coming out of the plane

B = magnetic field vertically downwards

q = negative charge

so from above equation of force we will have

[tex]F = (-q)[v(\hat k) \times B(-\hat j)][/tex]

[tex]F = -(qvB)\hat i[/tex]

so direction of force will be towards left
