Q. An electric dipole placed in a uniform electric field experiences maximum moment of couple when the dipole, is placed

Against the direction of the field

Towards the electric field

Perpendicular to the direction of the field

At $13 5^{\circ}$ to the direction of the field

$τ = PE sin θ$
For $θ = 9 0^{\circ}$
$τ =$ Max
