MCQ
An electromagnetic waves can be produced, when charge is:
- AMoving with constant velocity
- BMoving in a circular orbit
- CFalling in an electric field
- ✓both $(b)$ and $(c)$
✓
Answer
Correct option: D.
both $(b)$ and $(c)$
An accelerated charge is the source of electromagnetic waves $\text{(EMWs).}$ When the charge is in a circular motion, the direction of its velocity continuously changes and thus it is in accelerated motion and produces $\text{EMWs.}$
A charge falling in an electric field is accelerated by the electric force and thus produces $\text{EMWs.}$
