Identify the correct statement about the magnitudes of ground-state energies of hydrogen (H) and singly-ionised helium (He

^+

). (a)

|E_1(\mathrm{He}^+)| = 2\,|E_1(\mathrm{H})|

(b)

|E_1(\mathrm{He}^+)| = |E_1(\mathrm{H})|

(c)

|E_1(\mathrm{He}^+)| = 4\,|E_1(\mathrm{H})|

(d)

|E_1(\mathrm{He}^+)| = \dfrac12\,|E_1(\mathrm{H})|
