# Homework Help: What is the direction of the electric dipole moment?

### Soaring Crane

Point charges -5.00 C and +5.00 C are separated by distance 3.20 m, forming an electric dipole.

What is the direction of the electric dipole moment?

From + to -?

The electric dipole moment points from - to +.

If you chose the origin of the coordinate system in the point where you have the positive charge,then yes,the $\vec{p}$ will point towards the negative charge.

In the end it's a matter of convention.
