The unit of diploe moment is ------------

The unit of diploe moment is ------------ Correct Answer Coulomb. meter

CONCEPT :

  • An electric dipole is pair of equal and opposite charges separated by a distance of 2a, the midpoint of locations -q and + q is called the centre of the dipole.
  • The total charge of an electric dipole is zero
  • Electric dipole moment is the product of the magnitude of one charge multiplied by the distance of separation between the charge and is given by

P = 2a× q

Where P = diploe momentum , 2a = Distance between the charge,q = Charge

EXPLANATION :

  • Electric dipole moment is the product of the magnitude of one charge multiplied by the distance of separation between the charge and is given by

P = 2a × q

The unit of distance(a) is the meter and the unit of q is the coulomb, then the unit of dipole momentum is 

P = meter× Columb = Coulomb meter

  • The unit of diploe momentum is coulomb meter
  • Hence, option 4  is the answer
