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

A point charge q_1 = 86.5 uC is held fixed at the origin. A second point charge, with mass m = 5.90×10−2 kg and charge q2 = -2.95 uC, is placed at the location (0.323 m, 0)

1) Find the electric potential energy of this system of charges.

2)If the second charge is released from rest, what is its speed when it reaches the point (0.121 m, 0)?

2. Relevant equations

W = EPEa - EPEb

3. The attempt at a solutionI think the above equation is used in 1 but I'm not sure how to start it. For 2, I'm not sure how to figure out the problem using the x,y coordinates given. Any help would be appreciated
