NEET - 2017

In an electromagnetic wave in free space the root mean square value of the electric field is ${E}_{rms}=6$ V/m. The peak value of the magnetic field is

(a) 1.41$×{10}^{-8}T$

(b) $2.83×{10}^{-8}T$

(c) $0.70×{10}^{-8}T$

(d)

(b) Given root mean square value of electric field,

We know that, peak value of electric field,

${E}_{o}=\sqrt{2}{E}_{rms}$

Also, we know that, $c=\frac{{E}_{o}}{{B}_{o}}$

where, c= speed of light in vacuum
