Two positively charged spheres are in deep space where gravity is negligible. The spheres are held in place near
each other and then released from rest. What happens to the electric potential energy of the two-sphere system,
and in what direction do the spheres move, after they are released?
The electric potential energy increases as the spheres move farther away from each other.
The electric potential energy increases as the spheres move closer to each other.
The electric potential energy decreases as the spheres move farther away from each other.
The electric potential energy decreases as the spheres move closer to each other.
