Question

An electromagnetic wave can be produced, when charge is

(A) moving with a constant velocity

(B) moving in a circular orbit

(C) falling in an electric field

(D) both B and C

Answer 1

Correct option is D) both B and C

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
