QUESTION STATEMENT:द्विभाषी / Bilingual
नैनो-कण का आकार निम्नलिखित में से किसके बीच होता है ?
The size of a nanoparticle is between which of the following?
SELECT CORRECT OPTION:
A
100 एन-एम. से 1000 एन-एम.
100 nm to 1000 nm
B
0.1 एन-एम. से 1 एन-एम.
0.1 nm to 1 nm
C
1 एन-एम. से 100 एन-एम.
1 nm to 100 nm
Correct
D
0.01 एन-एम. से 0.1 एन-एम.
0.01 nm to 0.1 nm
Official Solution & Explanation:
Correct Answer: Option C(1 एन-एम. से 100 एन-एम.)
नैनो-कण (Nanoparticle) का आकार सामान्यतः 1 नैनोमीटर ($1\text{ nm}$) से 100 नैनोमीटर ($100\text{ nm}$) के मध्य होता है ($1\text{ nm} = 10^{-9}\text{ m}$)।
By definition, a nanoparticle has at least one dimension sized between 1 nanometer and 100 nanometers ($10^{-9}\text{ m}$ to $10^{-7}\text{ m}$).
