An electric dipole has a fixed dipole moment `vecp`, which makes angle `theta` with respect to x-axis. When subjected to a electric field `vecE_(1)=Ehati`, it experiences a torque `vecT_(1)=tauhatk`. When subjected to another electric field `vecE_(2)=sqrt(3)E_(1)hatj` it experiences a torque `vecT_(2)=-vecT_(1)`. the angle `theta` is:

A

`90^(@)`

B
