What is the direction of the net force on electric dipole placed in a non uniform electric field?
Hence the net force on the dipole is towards left and hence the dipole travels towards left. When a dipole is placed in a nonuniform electric field such that its dipole moment is in the direction of field, the dipole always travel in the direction of increasing field.
What happens to a dipole in a 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.
How do you determine the direction of an electric dipole moment?
The electric dipole moment, a vector, is directed along the line from negative charge toward positive charge. Dipole moments tend to point along the direction of the surrounding electric field.
What is net force on an electric dipole placed in a uniform electric field?
Therefore, the net force on the dipole is zero. Even if we change the orientation, the length and the charge of the dipole, the net force on the dipole will be equal to zero. Hence, the electric force on a dipole when it is placed in a uniform electric field is always zero.
What is the direction of dipole-with dipole moment?
The direction of force experienced by a positive charge due to an electric field is along the direction of the field while that by a negative charge is along the opposite direction to the field. As seen above, the dipole-with dipole moment $\\vec{p}$-is aligned in the opposite direction to that of increasing electric field.
What is the net force on a dipole in an electric field?
The forces on the two charges are equal and opposite, so there is no net force on the dipole. However, there is a torque: A dipole in an external electric field. (a) The net force on the dipole is zero, but the net torque is not.
What is the difference between inherent dipole and induced dipole?
Generally, the magnitude of an induced dipole is much smaller than that of an inherent dipole. For both kinds of dipoles, notice that once the alignment of the dipole (rotated or induced) is complete, the net effect is to decrease the total electric field in the regions inside the dipole charges ( (Figure) ).
Why is the dipole vector anti parallel to the electric field?
(2) the dipole vector can be anti parallel, parallel, or orthogonal to the Electric field, but since the electric field is a function of x, the dipole will eventually orient itself in a parallel position to the Electric field, and it will eventually move horizontally due to the difference in forces of the negative charge and the positive charge.
