Question

The fraction of volume occupied by the nucleus with respect to the total volume of an atom is :

• A. ${10}^{-15}$
• B. ${10}^{-5}$
• C. ${10}^{-30}$
• D. ${10}^{-10}$

Answer 1

The correct option is A ${10}^{-15}$

Volume fraction = $\frac{Volumeofnucleus}{Totalvol.ofatom}$

$=\frac{\left(4/3\right)\pi ({10}^{-13}{)}^3}{\left(4/3\right)\pi ({10}^{-8}{)}^3}={10}^{-15}$

So, the corret option is $A$
