$10^{-8}$ cm
D
$10^{-9}$ सेमी.
$10^{-9}$ cm
Official Solution & Explanation:
Correct Answer: Option B($10^{-7}$ सेमी.)
नैनोमीटर मीट्रिक प्रणाली में लंबाई मापन की इकाई है। $1 \text{ नैनोमीटर} = 10^{-9} \text{ मीटर} = 10^{-9} \times 10^2 \text{ सेमी.} = 10^{-7} \text{ सेमी.}$।
In the metric system, $1 \text{ nanometer} = 10^{-9} \text{ meter} = 10^{-9} \times 10^2 \text{ cm} = 10^{-7} \text{ cm}$.
