Two charges \[+3.2\times {{10}^{-19}}C\] and \[-3.2\times {{10}^{-9}}C\] kept 2.4 Å apart forms a dipole. If it is kept in uniform electric field of intensity \[4\times {{10}^{5}}volt/m\] then what will be its electrical energy in equilibrium [MP PMT 2003]

• A.            \[+3\times {{10}^{-23}}J\]
• B.                                      \[-3\times {{10}^{-23}}J\]
• C.            \[-6\times {{10}^{-23}}J\]
• D.                                      \[-2\times {{10}^{-23}}J\]
