Consider the following changes \(\mathrm{A}\rightarrow \mathrm{A}^{+} + \mathrm{e}^{-} : \mathrm{E}_{1}\) and \(\mathrm{A}^{+}\rightarrow \mathrm{A}^{2+} + \mathrm{e}^{-} : \mathrm{E}_{2}\). The energy required to pull out the two electrons are \(\mathrm{E}_{1}\) and \(\mathrm{E}_{2}\) respectively. The correct relationship between two energies would be
