356370 Assertion :
The positively charged nucleus of an atom has a radius of order of \({10^{ - 15}}\;m\).
Reason :
In \(\alpha\)-particle scattering experiment, the distance of closest approach for \(\alpha\)-particle \( \approx {10^{ - 15}}\;m\).

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
