(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

How much work is required to exchange the positions of q2 and q3?

q2 q3

q1

q1 and q2 are separated by a distance of 4.00 cm and q2 and q3 are separated by a distance of 2.00cm

The charge on q1 is 5.00nC, q2 is -5.00nC and q3 is 10.0nC

2. Relevant equations

U=(K(q2)(q3))/(r23) (#1)

U=qV (#2)

3. The attempt at a solution

Since the energy required to hold these charges at their positions is equation 1, my guess to simply found the energy holding the charges and that would be the energy required to move them... Guess I'm wrong...

Any help is appreciated...
