Quick Answer: What is the work done in rotating an electric dipole of dipole moment P from its position?

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

What is the work done to move an electric dipole from stable to unstable equilibrium position?

The work done in moving a dipole from its most stable to most unstable position in a 0.09 T uniform magnetic field is (dipole moment of this dipole = 0.5 Am^(2))

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?

does the energy of dipole increase or decrease in this process why? 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.

How do you find the work done in rotating an electric dipole?

Work Done To Rotate A Dipole In External Electric Uniform Field

  1. = PEsinTheta dTheta.
  2. When the dipole is rotated from 0 to {Theta } degrees, work done is given by.
  3. When Theta = 180^{0}\W = PE left [ 1-frac{cos}{180} right ]\W = PE left [ 1+1 right ]\W = 2PE.

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

Therefore we have that the work done by the external field in rotating the electric dipole through some angle is W=∫θfθiqEsinθrdθ+∫θfθiqEsinθrdθ. Therefore W=2∫θfθiqrEsinθdθ. where the electric dipole is given by →p=q→ℓ and has magnitude p=qℓ.

What is the work done in rotating the electric dipole from the most stable position to the most unstable position in a uniform electric field?

Work done in rotating an electric dipole is 6.4 × 104 J.

What is the work done in moving an electric dipole?

The direction of N is such as to line up p parallel to E. 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).

Is electric dipole moment scalar or vector?

Electric dipole moment is a vector quantity and it is represented as →p=q×→d in vector form.

Does a dipole experience a force when placed in the non uniform electric field?

When a dipole is placed in an electric field, the opposite charges on the dipole both experience a force due to the electric field. … Hence the dipole will experience both force and torque when placed in a non uniform electric field.

When a uniform field is a dipole experience?

Now, In a uniform electric field, both the point charges comprising the dipole will experience force, equal in magnitude and opposite in direction. Though the net force will always be zero, the torque will be in the same direction for both the charges. Hence torque will not be zero.

What is meant by electric dipole?

An electric dipole is defined as a couple of opposite charges q and –q separated by a distance d. … The simplest example of an electric dipole is a pair of electric charges of two opposite signs and equal magnitude separated by distance.
