Question

The direction of the dipole axis is defined as the line pointing from:

Options

• Perpendicular to the line joining the charges

• The centre outward to either charge

• The negative charge to the positive charge

• The positive charge to the negative charge

Answer 1

The dipole axis is the line passing through both charges, with its direction defined as pointing from the negative charge (−q) to the positive charge (+q). This convention ensures a consistent and standard orientation for dipole calculations and field analysis.
