Physics Question on Nuclei

The volume of atom in comparison to the volume of nucleus is of the order of

A

10510^5

B

101510^{15}

C

102510^{25}

D

103010^{30}

Answer

101510^{15}

Explanation

Solution

Radius of nucleus is of the order of 10−1510^{-15}m and radius of the atom is of the order of 10−1010^{-10}m . ∴\therefore (10−10)3(10−15)3=1015\frac{(10^{-10})^3}{(10^{-15})^3} = 10^{15}
