Vedclass · Answer

(B) The relationship between the amplitude of the electric field $(E_0)$ and the amplitude of the magnetic field $(B_0)$ for an electromagnetic wave in vacuum is given by the equation: $E_0 = c B_0$,where $c$ is the speed of light in vacuum.Given:$B_0 = 270 \ nT = 270 	imes 10^{-9} \ T$$c = 3 	imes 10^8 \ m/s$Substituting the values:$E_0 = (3 	imes 10^8 \ m/s) 	imes (270 	imes 10^{-9} \ T)$$E_0 = 810 	imes 10^{-1} \ NC^{-1} = 81 \ NC^{-1}$Therefore,the amplitude of the electric field is $81 \ NC^{-1}$.

If the amplitude of the magnetic field part of a harmonic electromagnetic wave in vacuum is $270 \ nT$,the amplitude of the electric field part of the wave is: (in $NC^{-1}$)
