Energy from the Sun falls on the Earth surface at the rate of $$1400\,\text{W m}^{-2}$$, which is known as solar constant. The respective rms values $$E_{\text{rms}}$$ and $$B_{\text{rms}}$$ of electric and magnetic fields in the sunlight, electromagnetic radiation, reaching Earth surface are. Take speed of light $$c = 3\times10^8\,\text{m s}^{-1}$$.

A

$$E_{\text{rms}} = 726.5\,\text{V m}^{-1},\ B_{\text{rms}} = 2.42\,\mu\text{T}$$

B

$$E_{\text{rms}} = 7260\,\text{V m}^{-1},\ B_{\text{rms}} = 242\,\text{nT}$$

C

$$E_{\text{rms}} = 1030\,\text{V m}^{-1},\ B_{\text{rms}} = 3.42\,\mu\text{T}$$

D

$$E_{\text{rms}} = 10300\,\text{V m}^{-1},\ B_{\text{rms}} = 342\,\text{nT}$$
