Use the diagram of a particle accelerator to answer the question. In particle accelerators such as the one shown, fields are employed to separate different subatomic particles. What type or types of fields are employed, and what characteristics do these particles need to have in order to be separated? (1 point) Responses Both electric and magnetic fields are applied. Particles need to have the same mass. Both electric and magnetic fields are applied. Particles need to have the same mass. Electric fields are applied. Particles need to come from the same type of atom. Electric fields are applied. Particles need to come from the same type of atom. Both electric and magnetic fields are applied. Particles need to be charged. Both electric and magnetic fields are applied. Particles need to be charged. Magnetic fields are applied. Particles need to lack charge.
Both electric and magnetic fields are applied. Particles need to be charged.
