A molecule of a substance has a permanent electric dipole moment of magnitude `10^(-29)` C-m. a mole of this substance is
polarised by applying a strong electrostatic field of magnitude `10^(6)` V/m. The direction of the field is suddenly changed by an angle of `60^(@)` Estimate the heat release by the substance in aligning its dipoles along the new direction of the field.
