Dipole in a uniform electric field
Dipole in a uniform electric field
When two charges in a dipole are separated by some distance , the forces acting at different points result in torque on the dipole .• The torque tries to align the dipole with electric field . Once aligned , the torque becomes 0 .
o Magnitude of torque = qE x 2a sinθ = 2qaE sinθ = pEsinθ . o
Direction of the torque = normal to the plane coming outwards .
