## Homework Statement

A charged particle traveling with a velocity v in a magnetic field B experiences a force F that must be:

A. parallel to v

B. perpendicular to only v

C. parallel to v-B

D. parallel to B

E. perpendicular to v x B

## Homework Equations

Requires this right hand rule, I believe:

## The Attempt at a Solution

Looking at the diagram, I'd say that the force should be perpendicular to both the force and the velocity and I had originally picked E. E is not correct, so would the right answer be B? But that would mean that force is not perpendicular to v and it very clearly is....
