Question

\(10 \AA\) equals ______.

Options

• 10 nm

• 100 nm

• 1000 nm

• \[\frac{1}{1000} \mathrm{~nm}\]

Answer 1

\(10 \AA\) equals 10 nm.

Explanation: 

Since,

\[ 1\,\text{Å} = 10^{-10}\,\text{m} \] and \[ 1\,\text{nm} = 10^{-9}\,\text{m} \]

∴ \[ 10\,\text{Å} = 10 \times 10^{-10}\]

\[\text{m} = 10^{-9}\]

\[\text{m} = 1\text{ nm}\]

So 10 Å = 1 nm.
