How does the electrical potential energy of a system of two point charges change when the charges are brought closer?

Increases

Decreases

Remains constant

Becomes zero

Potential energy U is determined by the formula U = k(q1q2)/r:

- Decreasing distance (r) increases U if both q1 and q2 have the same sign.

- For opposite charges, U decreases as r decreases.

- It's never zero unless charges are infinite distance apart.
