Question

The electric dipole moment of two equal and opposite charges (+q, −q) separated by distance 2l is:

विकल्प

• p = 2q/l, with SI unit C/m

• p = q(2l), with SI unit A·m²

• p = q/(2l), with SI unit C/m

• p = q(2l), with SI unit C·m

Answer 1

The electric dipole moment is p = q(2l), measured in C·m. This corresponds to the magnetic dipole moment m = IA, measured in A·m², in the analogy table.
