Question

Define an expression for torque acting on a eletric dipole in uniform

electric field. When the torque is maximum and minimum. Hence define

electric dipole moment also
​

Answer 1

Answer:

or τ=pEsinθ If θ=90∘,E=1, then p=τ Electric dipole moment is defined as the torque experienced by a dipole placed perpendicular to uniform electric field of unit strength

Answer 2

Answer:

Here's your answer

Explanation:

Let inside the uniform magnet field the electric dipole is placed. Let the force of qE is applied in the electric field on each charge of the dipole.

A couple rotate the dipole during to the equal and opposite force on the points of action. The torque(T) of the dipole is (qE×2dsinθ where d is the length of the dipole and θ is angle between the dipole and the direction of the field.

=>T=qE×2dSinθ

=>q×2d×Sinθ

=>p×ESinθ

T =p×E
