Question
Define electric dipole moment. Write its S.I. unit.
✓
Answer
Electric dipole moment is defined as the numerical product of charge and distance between the charges, and is directed from negative to positive charge.Alternate Answer
$\overrightarrow{\text{p}} = \text{q}( 2 \overrightarrow{\text{a}})$ Unit: coulomb metre or Cm.
$\overrightarrow{\text{p}} = \text{q}( 2 \overrightarrow{\text{a}})$ Unit: coulomb metre or Cm.
