    Electrostatics - Electric dipole

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    For two equal in magnitude but opposite charges +Q and -Q we can define a vector of dipole moment p, with the magnitude absolute value (p)=dxQ, where d is the distance between the charges. The direction of p is the direction from negative to positve charge (see figure)

    1.)What force acts on the dipole in a uniform electric field E.

    2.)What torque is acting on the dipole.
