Option 3 : B, D and E

  • Charged particles like proton, deuteron and alpha particles can be accelerated by a cyclotron. It is a particle oscillator which was invented in 1929-30 by Ernest Lawrence.
  • An electron cannot be accelerated by a cyclotron, because it has a very small mass. Due to this, its speed becomes very high and it quickly goes out of the step with the oscillating electric field.
  • A neutron cannot be accelerated by a cyclotron, because cyclotron can accelerate only the charged particle and neutron is not a charged particle.
