The product of the magnitude of the charge and the distance between the centres of positive and negative charge is called

Correct option is B

Correct Answer: B. Dipole

• The product of the magnitude of the charge (q) and the distance (d) between the centers of positive and negative charges is called the electric dipole moment (p).

  • Formula: p = q × d

• A system of two equal and opposite charges separated by a small distance is known as an electric dipole.

• Dipole Moment:

  • It is a vector quantity, directed from negative to positive charge.

  • SI unit: Coulomb-metre (C·m)

• Charge ratio: Not a standard physics term related to this context.

• Current flow: Movement of electric charges, unrelated to static dipole moments.

• Magnetic moment: Related to current loops and magnetic materials, not electric dipoles.
