Particles A (of mass m and charge Q) and B (of mass m and charge 5 Q) are released from rest with the distance between them equal to 0.4939 m. If Q= 31 uC, what is the kinetic energy of particle B at the instant when the particles are 2.4939 m apart? Answer in units of J.
I know that the initial kinetic energy is zero since the particles start from rest. I also know that you can relate the change in electrical potential to kinetic energy. I'm a little confused on how to set it up though.
