Question

56. A particle accelerator is a machine to increase the kinetic energy of
(A) electrically charged particles
(B) uncharged particles
(C) both charged and uncharged particles
(D) neutrons only​

Answer 1

Answer:

electrically charged particles

Answer 2

Answer:

Particle accelerator increase the kinetic energy of only electrically charged particles.

Explanation:

A particle accelerator is a machine that accelerates elementary particles to very high energies.

• They use electric fields or magnetic fields to speed up and increase the kinetic energy of a beam of particles.
• An accelerator can accelerate a particle with an electromagnetic field, provided that have an electric charge.
• In electrostatic accelerator, a charged particle like proton or electron accelerates between a gap between two electrodes when there is a potential difference between them.
• In electrodynamic accelerator, the electric fields spaced around the accelerator switch from positive to negative at a given frequency, creating radio waves that accelerate particles in bunches.
• There are two types of particle accelerators: linear accelerators and circular accelerators.
• Therefore particle accelerator increase the kinetic energy of only electrically charged particles.

So, the correct answer is option A.
