Now imagine you have several of such dipoles, and place them regularly between the plates. For this part of the pre-lab, you can ignore any interactions between the dipoles themselves, and think of each dipole as interacting with the electric field of the plates only. What will be different now

Dipole is two equal but opposite charges in one. As like charges repels and unlike charges attracts each other. If dipole are in electric field region, it positive side will be attracted to the negative field and vis-versa. This will result to different movement or stationary based on the orientation of the field. If the interaction between other dipole is considered this effect may be obstructed
