# Angle between magnetic field B and velocity of charge

**1. The problem statement, all variables and given/known data**

Find magnitude and direction of F of a charge moving through a magnetic field.

velocity: 5 m/s

charge: 2 C

B: 3 T (pointing out of the page when drawn)

**2. Relevant equations**

(vector)F=qv x B

(magnitude)F=qvBsinθ

**3. The attempt at a solution**

I know to use the equation for magnitude but I’m confused as to what the angle would be between v and B. Since the magnetic field is pointing out of the page, would the angle be 90°, making sin(90)=1?

Also, don’t know what direction that would be. Since I don’t know the direction of B, I’m not sure how to use the right hand rule to figure this out.
