## Homework Statement

A proton moves in a spiral path when enters a magnetic field of 5 T. If the pitch is 5 cm, find the angle between v and B.

## Homework Equations

F = B q v sin θ

F = m v

^{2}/ r

## The Attempt at a Solution

I am guessing that I need to break down the velocity into two components but still don't know how to use it. What is pitch actually?

Thanks
