Expert Solution
Step 1

An electric dipole is a pair of equal and opposite charges separated by a small distance and electric dipole moment measures its strength. It is a vector quantity. The electric dipole moment of a pair of equal and opposite charges is defined as the product of the magnitude of one of the charges and the distance between them.

Electric dipole moment =magnitude of one of the charges×separation between the charges
