Two small, identical metal balls with charges 7.0 µC and 14.0 µC are held in place 1.9 m apart. In an experiment, they are connected for a short time by a conducting wire. (a) What will be the charge on each ball after this experiment?
1. new charge on 7.0 µC ball = ? µC
2. ew charge on 14.0 µC ball = ? µC

(b) By what factor will the magnitude of the electrostatic force on either ball change after this experiment is performed?

= ?

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
