Physics - Magnetism Question with Solution | TestHub

A cyclotron is a device used to accelerate positively charged particles such as protons, deuterons, and alpha particles to very high energies.

It cannot accelerate neutral particles like neutrons because they do not experience any force in electric and magnetic fields.

It is not used to accelerate electrons (negatively charged particles) because of their very small mass. Electrons quickly attain relativistic speeds, causing their mass to increase and their frequency of revolution to change, which throws them out of phase with the oscillating electric field.

Therefore, a cyclotron is used to accelerate positively charged particles only.

Answer: accelerate positively charged particles only.
