Correct Answer - Option 4 : None of these
Concept:
Cyclotron:
- A cyclotron is a device used to accelerated positively charged particles (like α-particles, deuterons, etc.) to acquire enough energy to carry out nuclear disintegration, etc.
- It is based on the fact that the electric field accelerates a charged particle and the magnetic field keeps it revolving in circular orbits of constant frequency.
- The cyclotron frequency is given as,
\(⇒ f=\frac{Bq}{2\pi m}\)
Where B = magnetic field intensity, q = charge, and m = mass of the charged particle
Explanation:
- We know that a cyclotron is a device used to accelerated positively charged particles (like α-particles, deuterons, etc.).
- 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.
