Question

You decide to build a cyclotron (because you are bored) that will accelerate protons to 10% of the
speed of light. The largest vacuum chamber you can find is 50cm in diameter. What magnetic field
strength will you need?

Answer 1

well, the force to provide the centripetal acceleration might be found


Bqv=m v^2/r I would change m to relavistic mass, or real mass at that speed. Work it both ways.
