Q126 / 180 · KCET 2021 · Physics

The source of electromagnetic wave can be a charge

A
moving with a constant velocity
Correct answer
B
moving in a circular orbit
C
at rest
D
moving parallel to the magnetic field

Solution

Electromagnetic waves are produced by accelerated charges. In given options, only a charge particle moving in a circular orbit is in accelerated motion. So, it produces electromagnetic wave.

Hence, the correct answer is option: 'B'.
