A force of -4.4 * 10^3 N exists between a positive charge of 8 * 10^-4 C and a negative charge of -3 * 10^-4 C. The distance that separates the charges is _____ m.

The force between any two electrical charges is

(9 x 10⁹ N-m²/C²) · (one charge) · (the other charge) / (distance)²

(-4,400 N) = (9 x 10⁹ N-m²/C²) · (8 x 10⁻⁴ C) · (-3 x 10⁻⁴ C) / (distance)²

distance² = 0.491 m²

Distance = 0.7 meter
