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 `π/ 3` with the x-axis. If the electric field at P makes an angle `theta` with the x-axis, the value of `theta` would be ...........
Options:
(a) `π/ 3+tan^(-1)(sqrt 3/ 2)`
(b) `π /3`
(c) `(2π)/ 3`
(d) `tan^(-1)(sqrt3/2)`
