Magnetic Field

Here is the problem. How would I set up the equation to solve this?

A force of 5.78 10-16 N acts on an unknown particle traveling at a 90 angle through a magnetic field. If the velocity of the particle is 5.65 104 m/s and the field is 3.2 10-2 T, how many elementary charges does the particle carry?
