MCQ
An electromagnetic wave can be produced when the charge is
- Amoving in a circular orbit
- Bmoving with a constant velocity
- Cfalling in an electric field
- DBoth (a) and (c)
✓
Answer
- Both (a) and (c)
Explanation:
An accelerated charge is the source of electromagnetic waves (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 EMWs. A charge falling in an electric field is accelerated by the electric force and thus produces EMWs.
