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 = $3 \times 10^8 m s^{-1}$ |
$0.72 V m^{-1}$ $720 V m^{-1}$ $7200 V m^{-1}$ $7.20 V m^{-1}$ |
$720 V m^{-1}$ |
The correct answer is Option (2) → $720 V m^{-1}$ |
