An electric dipole of dipole moment \( 6 \times 10^{-6} \, \text{cm} \) is placed in uniform electric field of magnitude \( 10^{6} \, \text{V/m} \). Initially, the dipole moment is parallel to electric field. The work that needs to be done on the dipole to make its dipole moment opposite to the field, will be __________ \( \text{J} \).
