What is work done in rotating an electric dipole in a uniform electric field through an angle?

W=2pE(1−cosθ)

What is the expression for total work done in rotating an electric dipole?

When an electric dipole of moment P is rotated to an orientation where it makes an angle of£ with the external electric field E starting from its initial orientation€, the expression for work done (and hence the electrostatic potential energy stored) is u= -pE (cos£-cos€).

What is the work done in rotating a dipole from stable to unstable equilibrium?

Work done in rotating an electric dipole is 6.4 × 10-4 J.

What will be the work done in rotating an electric dipole through 360 degree?

4. What is the work done in turning an electric dipole through 360°? = 0.

What is the expression for total work done in rotating an electric dipole from its equilibrium position to an angle theta with the uniform field?

Torque=rqE sin(theta), now this rq is nothing but the dipole moment p. Work done by the torque is given by Integration[Torque. d(theta)] with upper limit Beta(final angle) and lower limit Alpha(initial angle).

What is work done by the electric field on the dipole?

Energy of a dipole in electric field: We calculate the energy of a diple in a electric field E by bringing the dipole from infinity and placing it such that −q charge is at r. Work done is ( E = −∇V (r)), U = −q V (r) + q V (r + s).

What is the work done in rotating a dipole from its unstable equilibrium to stable equilibrium to stable equilibrium does the energy of the dipole increases or decreases?

Potential energy of dipole is the energy possessed by the dipole by virtue of its particular position in the electric field. Hence, work done , W = -2pE and hence the energy of the dipole decreases in this process.

What is the work required to rotate an electric dipole from its most stable to the most unstable condition in uniform electric field?

The potential energy of the dipole is minimum when p is aligned with the field E (ϴ = 0) and by convention is taken as – pE , and maximum when p is opposed to the field (ϴ = 180) when it is + pE. Note that ϴ = 0 corresponds to the position of stable equilibrium, and ϴ = 180 to the position of unstable equilibrium.

What is the work done in rotating a dipole from its unstable equilibrium to stable equilibrium does the energy of the dipole increase or decrease?

What is meant by electric dipole derive the formula for work done to rotate the electric dipole in electric field?

Work done if dipole rotated from 180 degree When Θ=1800W=PE[1−cos180]W=PE[1+1]W=2PE. The dipole is said to be stable when the dipole is aligned in the direction of the electric field.
