# Solve problem using energy conservation and momentum conserv

Two point charges having charges q1=5 µC and q2=7 µC and masses m1=2 grams and m2=3 grams, respectively, are released (in deep space) from rest when they are r=21 cm apart. Determine how fast each charge will be moving when they are very far apart frome each other.

#### Solution Preview

To calculate this, we will use electrostatic potential energy.

Now, we know that Epot=Ekin, because energy is conserved, and the potential energy of the system will equal the amount of work required to ...

#### Solution Summary
