Solution

## The correct option is D π3+tan−1√32An electric dipole is placed along the x−axis at the origin P.A point P is a distance of 20cm from this origin such that OP makes an angle 600 with x−axis. If electric field at P makes on angle θ with x−axis, thenBy the fig.θ=60+αNow, resolving E into its componentsEcosα=2Pcos6004πϵ0r3⟶(1)Esinα=Psin6004πϵ0r3⟶(2)Dividing (2) by (1)tanα=12tan600tanα=√32or, α=tan−1(√32)Now, θ=60+α =π3+tan−1(√32)
