The sunlight reaching the earth has maximum magnetic field $2.4 \mu T$. What is the maximum electric field in this light? Speed of light = $3 \times 10^8 m s^{-1}$
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → $720 V m^{-1}$
The maximum electric field $(E_{max})$ is -
$E_{max}=C×B_{max}$
$=3×10^8×2.4×10^{-6}$
$=720V/m$
