Electric Potential Energy of a Charge System
Four identical point charges, each with charge q = 2.0 nC, are initially positioned at the vertices of a square with a side length of a = 10 cm. If one of these charges is moved to the center of the square, what is the resulting change in the electric potential energy of the system?

B
Increases by 5.52 × 10⁻⁷ J
C
Increases by 1.08 × 10⁻⁷ J
D
Decreases by 3.24 × 10⁻⁷ J
