हिन्दीThe diameter of the Earth is \( 1.28 \times 10^7\text{ m} \) and the diameter of a hydrogen atom is \( 1.06 \times 10^{-10}\text{ m} \). How many orders of magnitude is the diameter of the Earth larger than that of a hydrogen atom?
Correct answer · Option 2
\( 17 \)
Explanation
Order of magnitude of Earth's diameter is \( 10^7\text{ m} \) and that of a hydrogen atom is \( 10^{-10}\text{ m} \). Difference \( = 7 - (-10) = 17 \) orders of magnitude.
