🤓 Based on our data, we think this question is relevant for Professor Nair's class at UIW.
The two charges Q are fixed at the vertices of an equilateral triangle with sides of length a as shown.
The work required to move a charge q from the other vertex to the center of the line joining the fixed charges is
1. W = √ 2kQq / a
2. W = 0
3. W = 2kQq / a
4. W = 4kQq / a
5. W = kQq / a
6. W = 6kQq / a
