Practice session

Two small conductive spheres in vacuum carry electrostatic charges of q₁ = +2.0 μC (+2.0 × 10⁻⁶ C) and q₂ = -4.0 μC (-4.0 × 10⁻⁶ C) and are separated by a center-to-center distance of r = 0.30 m. Taking Coulomb's electrostatic constant as k = 9.0 × 10⁹ N·m²/C², what are the magnitude and nature of the electrostatic force between them?
