The expression for torque '\(\vec{\tau}\)' experienced by an electric dipole of dipole moment '\(\vec{P}\)' in an external uniform electric field '\(\vec{E}\)' is given by :
1
\(\vec{\tau}=\vec{P}.\vec{E}\)
2
\(\vec{\tau}=\frac{\vec{P}}{\vec{E}}\)
3
\(\vec{\tau}=\frac{\vec{E}}{\vec{P}}\)
4
\(\vec{\tau}=\vec{P}\times \vec{E}\)
