Dipole in a uniform external field

The video tutorial explains the concept of a uniform electric field, where the field strength is consistent at every point. It discusses the behavior of a permanent dipole in such a field, highlighting that the net force on the dipole is zero, but a torque is present due to the separation of charges. The torque's magnitude is determined by the forces and their perpendicular distance. In non-uniform fields, the net force is non-zero, and the dipole experiences a force depending on its orientation relative to the field. The video also covers vector notation for torque and the conditions under which the net torque is zero.

What is meant by a uniform electric field?

Describe the relationship between the dipole moment and the electric field strength.

Explain the concept of torque on a dipole in a uniform electric field.

What happens to the torque when the dipole moment is parallel or antiparallel to the electric field?

How does the orientation of the dipole moment affect the net force in a non-uniform electric field?
