The cyclotron at TRIUMF accelerates protons from a central injection point outward along an increasing spiral path. Magnets direct the protons around and around until they travel outwards far enough to leave the magnetic field. The protons reach a final speed of 1.1×108 m/s when they leave the cyclotron. Suppose inside the cyclotron there is a uniform magnetic field downwards, with strength 0.4 T. What is the magnitude of the magnetic force, in piconewtons, on the proton at the moment it leaves the cyclotron? Assume the proton is travelling eastwards when that happens. Answer in piconewtons. Also state what direction was the force on the proton the moment it left the magnetic field. Be clear and show all your work.
