**[SOLVED] electrostatics, ONE TEENSY little problemo! please HELPPPPP thanks!**

## Homework Statement

Two charges of q1 = 1.3 µC and q2 = -2.6 µC are d = 0.60 m apart at two vertices of an equilateral triangle as in Figure P16.56.

(d) What is the work required to move a 3.2 µC charge from infinity to point P?

## Homework Equations

kq1q2 / r = Ue

## The Attempt at a Solution

i tried 0 and used 19,478.33 V as voltage, but i don't really understand how to do this problem, like you don't need to tell me the answer, i just want to be able to understand how to find something when the distance is infinity.
