PHY2061 R. D. Field Department of Physics chp25_6.doc University of Florida The Electric Dipole +Q -Q d An electric "dipole" is two equal and opposite point charges separated by a distance d. It is an electrically neutral system. The "dipole moment" is defined to be the charge times the separation ( dipole moment = Qd ). Example Problem: +Q -Q d q x A dipole with charge Q and separation d is located on the y-axis with its midpoint at the origin. A charge q is on the x-axis a distance x from the midpoint of the dipole.

Unformatted text preview: What is the electric force on q due to the dipole and how does this force behave in the limit x >>d ( dipole approximation )? Example Problem:-Q +Q d x A dipole with charge Q and separation d is located on the x-axis with its midpoint at the origin. A charge q is on the x-axis a distance x from the midpoint of the dipole. What is the electric force on q due to the dipole and how does this force behave in the limit x >>d ( dipole approximation )?...
