Polar molecules are the molecules:
1. | that acquires a dipole moment only when the magnetic field is absent. |
2. | has a permanent electric dipole moment. |
3. | has zero dipole moment. |
4. | that acquire a dipole moment only in the presence of an electric field due to displacement of charges. |
A dipole is placed in an electric field as shown. In which direction will it move?
1. | towards the left as its potential energy will decrease. |
2. | towards the right as its potential energy will increase. |
3. | towards the left as its potential energy will increase. |
4. | towards the right as its potential energy will decrease. |
