1. Determine the electrical force of attraction between two balloons with separate charges of +3.5 x 10"3 t'.' and 2.9 1' HI"3 (I when separated a distance of [1.65 m. 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+x 10'? C and they are separated by a distance of ll m. Determine the electrostatic force and gravitational force between two electrons 10'1" m. apart [i.e. the forces felt inside an atom}. Two-point charges are located on the saxis of a coordinate stratemuqr1 = 1.5 at: is at x = +2.5 cm. and q2 = 2.D at: is at x = +41] cm. What is the total electric force exerted byes1L and gr2 on a charge q3 = 4.5m: at: =? The electrostatic force between two charged spheres of +3nC and +4nC resltiectisetglr is D,D4N. What is the distance between the spheres
