Question -
An electric dipole is placed along the x - axis at the origin O . A point P is at a distance of 20cm from this origin such that OP makes an angle π3 with the x-axis. If the electric field at P makes an angle θ with the x-axis, the value of θ would be
Options:
A .  π3
B .  π3+tan−1(√32)
C .  2π3
D .  tan−1(√32)
E .  If assertion is false but reason is true.
Answer: Option B : B θ=π3+α where tanα=12tanπ3⇒α=tan−1√32 So, θ=π3+tan−1√32
