Question

Out of the following options, which one can be used to produce a propagating electromagnetic wave?

• A. A stationary charge
• B. A chargeless particle
• C. An accelerating charge
• D. A charge moving at constant velocity

Answer 1

The correct option is C An accelerating charge

A charge particle at rest produce only electric field and when moving at constant velocity then produce both electric and magnetic field.

Whereas, when the charge particle is in accelerated motion, then both the electric and magnetic field will change, it then produces an electromagnetic wave.

Hence, option $\left(C\right)$ is the correct answer.
