Question

An electric dipole is placed at the origin and is directed along the x -axis. At a point P , far away from the dipole, the electric field is parallel to the y -axis. O P makes an angle θ with the x -axis, then -, t a n θ = 3, t a n θ = 2, θ = 45 °, None of these

MARKS App · Accepted Answer

Direction of electric field from axis of dipole is given by = θ + t a n – 1 t a n θ 2 Here given that E is along y -axis. θ + t a n – 1 t a n θ 2 = π 2 t a n θ 2 = c o t θ t a n θ = 2 c o t θ ⇒ t a n 2 θ = 2 ∴ t a n θ = 2
