An electric sipole has a fixed dipole moment ` vecp ` , which makes angle ` theta ` respect to x - axis when subjected to an electric field ` vecE_(1) = W hati ,` it experiences a torque ` vecT _(1) = tau hatk ` . When subjected to another electric field `vec E_(2) = sqrt(3) E_(1) hatj ` it experience a torqure ` vecT_(2)= - vecT_(1) ` . The angle ` theta ` is
