Question
An electromagnetic waves can be produced, when charge is:

Answer

  1. both (b) 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.

We are able to obtain fairly large currents in a conductor because(a) The electron drift speed is usually very large(b) The number density of free electrons is very high and this can compensate for the low values of the electron drift speed and the very small magnitude of the electron charge(c) The number density of free electrons as well as the electron drift speeds are very large and these compensate for the very small magnitude of the electron charge(d) The very small magnitude of the electron charge has to be divided by the still smaller product of the number density and drift speed to get the electric current
