(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A proton enters a uniform magnetic field of strength B. Sketch it subsequent motion and derive an expression for the time, t, spent in the magnetic field.

2. Relevant equations

[tex]F=qvB=mv^{2}\div r[/tex]

3. The attempt at a solution

I calculated the period of the particle in the field as:

[tex]T= 2 \pi m\div qB[/tex]

I don't know if this is what they want or if there's a way to calculate the total time.
