An electric point dipole is placed at the origin O with its dipolemoment along the X-axis . A pointA is at a distance r from the origin such that OA makes an angle pi//3 with the X -axis if the electric field vec( E) due to the dipole at A makes an angle theta with the positive X-axis, the value of theta is

Answer»
