A balloon rubbed against denim gains a charge of -3.0 uC. What is the electric force between the balloon and the denim when the two are separated by a distance of 6.0 cm? (As- sume that the charges are located at a point.) The value of the Coulomb constant is 8.98755 x 10^9 N •m²/C^2. Include direction of the force.
