Determine the electrical force of attraction between two balloons that are charged with the opposite type of charge but the same quantity of charge. The charge on the balloons is 1.2 x 10-8 C and they are separated by a distance of 0.40 m.

2. Determine the electrical force of attraction between two balloons that are charged with the opposite type of charge but the same quantity of charge. The charge on the balloons is 6.5 x 10-7 C and they are separated by a distance of 2.50 m.

3. Determine the electrical force of attraction between two balloons with separate charges of +3.5 x 10-8 C and -2.9 x 10-8 C when the electrical force is 2.16 x 10^-5

4. Determine the electrical force of attraction between two balloons with separate charges of +2.5 x 10-8 C and -1.9 x 10-8 C when separated a distance of 1.65 m.

5. Determine the electrical force of attraction between two balloons with separate charges of +2.6 x 10-4 C and -1.9 x 10-4 C when the electrical force is 1052N.

6. Joann has rubbed a balloon with wool to give it a charge of -3.0 x 10-4 C. She then acquires a plastic golf tube with a charge of +6.0 x 10-7 C localized at a given position. She holds the location of charge on the plastic golf tube a distance of 150.0 cm above the balloon. Determine the electrical force of attraction between the golf tube and the balloon.
