Electric Dipole Moment Vector Calculation

[lacar213]

Homework Statement

Two opposite point charges of magnitude 1.90e-6 C are located near the origin. The positive charge is at (1.50, 1.50) mm and the negative charge is at (−1.50, −1.50) mm. What is the magnitude of the dipole moment vector for this pair of charges?

Homework Equations

p = qd
d = sqrt(x^2 + y^2)

The Attempt at a Solution

I solved d = .002121
solved p = 4.03051e.9

Try calculating d again. It's the distance between the two charges.

Also, including units with the values would be a good habit to get into.
