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\(\alpha\)-particle scattering experiment, the distance of the closest approach for \(\alpha\)-particle is \(\approx 10^{-15}~m\).
 
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).

An ionised \(H\)-molecule consists of an electron and two protons. The protons are separated by a small distance of the order of angstrom. In the ground state:

(a) the electron would not move in circular orbits.
(b) the energy would be \(2^{4}\) times that of a \(H\)-atom.
(c) the electron's orbit would go around the protons.
(d) the molecule will soon decay in a proton and a \(H\)-atom.

1. (a), (b)
2. (a), (c)
3. (b), (c), (d)
4. (c), (d)
