An electric dipole of moment \(\vec{p}\) is placed in a uniform electric field \(\vec{E}\) . Then (i) the torque on the dipole is \(\vec{p} \times \overrightarrow{\mathrm{E}}\) (ii) the potential energy of the system is \(\vec{p} . \overrightarrow{\mathrm{E}}\) (iii) the resultant force on the dipole is zero. Choose the correct option.
