Question

What is the direction of the force for a negative charge moving downward in a magnetic field pointing to the left?

Answer 1

Step-by-step explanation:

just took on edge

Answer 2

A charge is moving downwards so let say this downwards direction is along -z direction

Also here magnetic field is given towards left so let say left direction is towards -x direction

now we have to find force direction so as we know that force on a moving charge is given by

`F = q(\vec v * \vec B)`

so here we have

`F = q(v(-\hat k) * B(-\hat i))`

`F = qvB(\hat j)`

so force is along +Y direction
