## Homework Statement

Consider a charged particle moving with velocity v through a magnetic field B. Answer True or False.

1) The magnetic field B is always perpendicular to the acceleration a of the particle.

2) The magnetic force F is always perpendicular to the acceleration a of the particle.

3) The acceleration a of the particle is always perpendicular to the velocity v.

4) The force F exerted by the magnetic field is always perpendicular to the velocity v.

## Homework Equations

F = qv x B (cross product, magnetic force on a moving charged particle).

## The Attempt at a Solution

I tried 1) false 2) true 3) false 4) true and FFFT, but it was wrong. I was sure about my first answer since the magnetic force is always perpendicular to B and V.
