Explain why a proton travels in a semicircular path in a dee in a cyclotron |
The force on the proton due to the magnetic field in the Dee is perpendicular to the motion of the proton. It acts as a centripetal force, causing circular motion |

Charged Particles of different masses are accelerated from the same point to a detector, travelling a distance L. How can the mass of the particles be deduced from measuring the time intervals of each as it travels? |
All Particles are given the same (kinetic) energy when accelerated. Higher mass particles will therefore travel slower, taking a longer time to travel |
