An electric dipole has a pair of equal and opposite point charges $q$ and $-q$ separated by a distance $2 x$. The axis of the dipole is defined as

• A

  direction from positive charge to negative charge
• Correct answer
  B

  direction from negative charge to positive charge
• C

  perpendicular to the line joining the two charges drawn at the centre and pointing upward direction
• D

  perpendicular to the line joining the two charges at the centre and pointing downward direction

Solution

The axis of the electric dipole is directed along the direction of dipole moment and the direction of electric dipole moment is taken from negative charge to positive charge.

Hence, the correct answer is option: 'B'.
