Correct answer: D

As V ∝\propto∝ r3

⇒\Rightarrow⇒ Vatom = ratom3rnucleus3{{r_{atom}^3} \over {r_{nucleus}^3}}rnucleus3​ratom3​​ ×\times× Vnucleus

= (10−10)3(10−15)3{{{{\left( {{{10}^{ - 10}}} \right)}^3}} \over {{{\left( {{{10}^{ - 15}}} \right)}^3}}}(10−15)3(10−10)3​ ×\times× Vnucleus

= 1015 ×\times× Vnucleus
