An electric dipole is placed along the x-axis at the origin `O.A` point `P` is at a distance of `20 cm` from this origin such that `OP` makes an angle `(pi)/(3)` with the `x`-axis. If the electric field at `P` makes an angle `theta` with x-axis, the value of `theta` would be
A. `(pi)/(3)`
B. `(pi)/(3) + tan^(-1)((sqrt(3))/2)`
C. `(2pi)/(3)`
D. `tan^(-1)((sqrt(3))/(2))`
