alleryElectromagnetic waves are produced by charges that are:
AUncharged
BNeutralised
CAccelerated
DMotionless
Answer & Solution
Correct answer: C. Accelerated
1. A charge sitting still gives only a static field.
2. A charge moving steadily gives a steady magnetic field.
3. Only accelerated charges radiate electromagnetic waves.
4. So the answer is accelerated.
