Question

The direction of electric field intensity (@) at a point on the equatorial line of an
electric dipole of dipole moment () is
1) Along the equatorial line towards the dipole
2) Along the equatorial line away from the dipole
3) Perpendicular to the equatorial line and opposite to P
4) Perpendicular to the equatorial line and parallel top​

Answer 1

The correct answer for  this question is option (4) Perpendicular to the equilateral line and parallel to P

Explanation :

• In an electric dipole at an equilateral position , the electric field component is perpendicular to the dipole moment .
• This is because the two opposite and equal charges gets cancelled while the horizontal component for the same gets added .
