A water molecule has a permanent dipole moment of 6.20×10-30 Cm, and if you put one in an electric field it will feel a torque and try to rotate (this is essentially how a microwave oven works, although that electric field oscillates). What is the torque on the molecule if its dipole moment is oriented at 27.9° with respect to the electric field, which has a strength of 2.95×104 N/C?

Electric dipole moments of molecules are often measured in debyes (D), where 1 D = 3.34 ⋅ 10–30 C m1 𝐷 = 3.34 · 10–30 C m . For instance, the dipole moment of hydrogen chloride gas molecules is 1.05 D. Calculate the maximum torque such a molecule can experience in the presence of an electric field of magnitude 223 N/C.

A water molecule has an electric dipole moment 6.4 x 10 cm when it is in vapour state. The distance in metre between the centre of positive and negative charge of the molecule is (a) 4x10-10 104 10-12 (b) 4 x 10-11 (d) 4 x 10-13
