List of top Physics Questions on The Electric Field Due to an Electric Dipole

An electric dipole of moment \(\vec{p}\) is placed in a uniform electric field \(\vec{E}\). Then

• [(i)] the torque on the dipole is \(\vec{p}\times\vec{E}\).
• [(ii)] the potential energy of the system is \(\vec{p}\cdot\vec{E}\).
• [(iii)] the resultant force on the dipole is zero.

Choose the correct option.

An electric dipole of moment \(P\) is placed along the direction of electric field \(E\). The work done in deflecting the dipole through \(180^\circ\) is equal to
