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

A) \[{{E}_{1}}<{{E}_{2}}\]        

B)        \[{{E}_{1}}={{E}_{2}}\]

C) \[{{E}_{1}}>{{E}_{2}}\]        

D)        \[{{E}_{1}}\ge {{E}_{2}}\]
