Assertion:  When a charged particle moves in a circular path. It produces electromagnetic wave.

Reason:  Charged particle has acceleration

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

  • If both assertion and reason are true but reason is not the correct explanation of assertion.

  • If assertion is true but reason is false.

  • If both assertion and reason are false

Solution

A.

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

Magnetic forces can cause charged particles to move in circular or spiral paths. Particle accelerators keep protons following circular paths and magnetic force. The magnetic force is perpendicular to the velocity and so velocity changes in direction but not in magnitude.

Accelerated charges radiate electromagnetic waves.
