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

I need help with a problem I was just given an equation (F =q VxB )at the end of class and expected to solve a problem but im not sure what to do.
A proton is moving at speed 5x106m/s in the magnetic field of magnitude 6x10-2 T indicated in the diagram. a) find the magnitude and direction of the initial magnetic force on the proton. b)what is the magnitude of the acceleration of the proton?
The diagram and work are in the work below. I was not sure what to do so i looked through the book and found another equation.

2. Relevant equations
