If an electric dipole is placed in a uniform external electric field and released, how would you discuss its motion?
Still have a question? Ask your own!
When an electric dipole is released in a uniform external electric field, the dipole experiences torque.(rotates)
Due to translatory forces acting in opposite directions there is zero net force. As a result the dipole will not experience any linear acceleration.
The dipole acts as a couple as the two forces act on the dipole at different points. Hence it experiences torque(rotation) till it attains stable equilibrium. (θθ becomes 00, torque becomes 00)
When electric feild is in direction of the dipole moment of the dipole,the dipole attains stable equilibrium(θ=0)(θ=0). If electric feild and dipole moment are opposite in direction ,the dipole is in unstable equilibrium.(θ=180)(θ=180)
Torque=PEsinθTorque=PEsinθ
Where,
PP=dipole moment.
EE=electric field intensity.
θθ=angle between the electric field and dipole moment.
