A molecule of lithium fluoride (LiF) permanent dipole moment. The molecule is placed in a uniform electric field of strength 10^4 N/C, and the difference between the maximum and minimum potential energies of the dipole is measured to be 4.4 x 10^ -25 J. Describe the orientations of the LiF dipole moment in relation to the applied electric field when it has maximum and minimum potential energies. What is the electric dipole moment of the LiF molecule?
