- ACharge only.
- BCharge and length of a dipole.
- CCharge, length of a dipole and dielectric constant of the medium.
- DCharge and dielectric constant of the medium.
Explanation:
Dipole is defined as two equal but opposite charges, kept at a small distance and having a dipole moment. The dipole moment is simply the product of the electric charge and length of the dipole. The dielectric constant of the medium doesn’t affect the dipole moment i.e. dipole moment of an electric dipole will be the same in water as well as in the air.
