Given below are two statements:
Assertion (A): |
The positively charged nucleus of an atom has a radius of almost \(10^{-15}~\text{m}\). |
Reason (R): |
I n \(\alpha\)-particle scattering experiment, the distance of the closest approach for \(\alpha\)-particle is \(\approx 10^{-15}~\text m\). |
1. |
Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. |
Both (A) and (R) are True but (R) is not the correct explanation of (A). |
