A thin stream of water makes an excellent charge detector. By rubbing a balloon on your hair, you give the balloon a negative charge. Bringing the charged balloon close to the water stream, you observe that the water stream is deflected-the negatively charged balloon attracts the water. You then rub a small drinking glass with your silk pajamas -this gives the glass a positive charge. After having removed the balloon, you bring the glass close to the stream of water. What does the water do? a. The water is attracted to the glass. b. The water is repelled by the glass. c. The water is not deflected at all.

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?
