Answer 1

$\huge\underline{\underline{\bf \orange{Question-}}}$

The Amplitude of the magnetic field of an Electromagnetic wave is ${\sf 5×10^{-7}T}$ . What is the Amplitude of the electric field ${\sf (3×10^8m/s)}$.

$\huge\underline{\underline{\bf \orange{Solution-}}}$

$\large{\rm We \: know \; that -}$

✪$\large{\boxed{\bf \blue{\dfrac{E}{B}=c} }}$

$\implies{\sf \dfrac{E}{5×10^{-7}}=3×10^8}$

$\implies{\sf E = 3×10^8×5×10^{-7}}$

$\implies{\sf E =15×10}$

$\implies{\bf \red{Electric \:Field(E) = 150\:N/C}}$

$\huge\underline{\underline{\bf \orange{Answer-}}}$

Electric field is ${\bf \red{150N/C}}$.
