A) \[{{10}^{10}}\]
B) \[{{10}^{15}}\]
C) \[{{10}^{1}}\]
D) \[{{10}^{5}}\]
Correct Answer: B
Solution :
Radius of atom \[\approx \,\,{{10}^{-10}}\,m\] Radius of nucleus \[\approx \,\,{{10}^{-15}}\,m\] Ratio of volume of atom to volume of nucleus \[=\frac{volume\,of\,atom}{volume\,of\,nucleus}\] \[=\frac{\frac{4}{3}\pi r_{1}^{3}}{\frac{4}{3}\pi r_{2}^{3}}\] \[={{\left( \frac{{{10}^{-10}}}{{{10}^{-15}}} \right)}^{3}}={{10}^{15}}\]
