Three charges +q, +q and -2q are placed at the vertices of an equilareral triagle. What is the dipole moment of the system?

Explanation

To find the dipole moment of the system consisting of three charges +q, +q, and -2q placed at the vertices of an equilateral triangle, we can follow these steps:

### Step 1: Understand the Configuration
We have three charges:
- Charge A: -2q (at vertex A)
- Charge B: +q (at vertex B)
- Charge C: +q (at vertex C)
