1. Determine the electrical force of attraction between two balloons with separate charges of +3.5 1: 10-8 C and- 2.9 x: 103 C when separated a distance of 0.65 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+6x 10-? C and they are separated by a distance of 0.50 m. 3. Determine the electrostatic force and gravitational force between two electrons 1010 m apart (i.e. the forces felt inside an atom). 4. Two-point charges are located on the swaxis of a coordinate system: q1=1.5 HC is at x = +2.5 cm, and q2=-2.0 n6 is at x = +4.0 cm. What is the total electric force exerted by: qi and 192 on a charge q3=4.5 :16 at x = D? 5. The electrostatic force between two charged spheres of +3nC and +4nC respectively is 0.04N. What is the distance between the spheres
