# Particle’s path in magnetic field

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

A charge enters a magnetic field. Draw the path the charge will follow and find the radius and period of the particle’s path.

v=10m/s (drawn as a straight line pointing right)

q=3c

B=4T (points outward)

**2. Relevant equations**

I’m not sure.

**3. The attempt at a solution**

The charge is drawn as positive. Wouldn’t I need the mass for an equation? I don’t know what the mass would be. Would it just be the mass of a proton?

Also, anyone know what equation I would use?
