Assertion : A charged particle can be accelerated in a cyclotron by the alternate distribution of the field. Reason : Energy of charged particle is increased by the field applied.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion.

Step-by-step solution

Cyclotron is used to accelerate charged particles to high energies. It uses both electric and magnetic fields together to increase the energy of the charged particle.
