Question

Which of the following statements about dipole moment is not true?

• A. The dimensions of dipole moment is $[L T A]$
• B. The unit of dipole moment is $C \,m$
• C. Dipole moment is vector quantity and directed from negative to positive charge
• D. Dipole moment is a scalar quantity and has magnitude charge equal to the potential of separation between charge

Answer 1

Answer: (D)

Dipole moment is a scalar quantity and has magnitude charge equal to the potential of separation between charge

Answer 2

Dipole moment is a vector quantity and has magnitude of $2qa$ and it is in the direction of the dipole axis from $-q$ to $q$.
