List-I shows different dependencies of energy E on atomic number Z. List-II describes the corresponding physical phenomena. Match List-I with List-II: List-I (P) E ∝ Z2 (Q) E ∝ Z(Z - 1) (R) E ∝ (Z - 1)2 (S) E is nearly independent of Z List-II (1) Electrostatic repulsion energy in nucleus (2) Binding energy per nucleon (approximately constant) (3) Characteristic K-α X-ray photon energy (4) Energy of levels for hydrogen-like ions (5) Energy released in beta decay
