## Homework Statement

A dipole sits a distance d above a point charge q which is located at the origin of our coordinate system. In (a) it is aligned in the z direction and in (b) in the y direction. Calculate the energy, force, and torque of the dipole in the field of the charge.

(see attachment)

## Homework Equations

U=-[tex]\vec{P}\bullet\vec{E}[/tex] Energy

[tex]\tau=\vec{P}\times\vec{E}[/tex] Torque

## The Attempt at a Solution

For (b) it is clear that the Torque is 0, but that is about all I've figured out so far...
