Q1

The electric field of an electromagnetic wave in free space is represented as \(\vec{E}={E}_{0}\cos (\omega t-kz)\overset{^}{i}\). The corresponding magnetic induction vector will be :

a

\(\vec{B}=\frac{{E}_{0}}{C}\cos (\omega t-kz)\overset{^}{j}\)

b

\(\vec{\mathrm{B}}={\mathrm{E}}_{0}C\cos (\omega \mathrm{t}+\mathrm{kz})\overset{^}{j}\)

c

\(\vec{\mathrm{B}}=\frac{{\mathrm{E}}_{0}}{\mathrm{C}}\cos (\omega \mathrm{t}+\mathrm{k}z)\overset{^}{j}\)

d

\(\vec{\mathrm{B}}={\mathrm{E}}_{0}C\cos (\omega \mathrm{t}-\mathrm{k}z)\overset{^}{j}\)
