The angle between the dipole moment and electric field at any point on the equatorial plane is

Options

  1. A( 0^ )
  2. B( 90^ )
  3. C( 180^ )
  4. D( 45^ )

Correct answer

C. ( 180^ )

Step-by-step solution

Dipole moment points in a direction from negative charge towards positive charge as shown in the figure. At equatorial plane, the electric field points in a direction just opposite to that of dipole moment. Hence the angle between dipole moment and electric field at any point on equatorial plane is (180^ ).
