Three Styrofoam balls are suspended from thin threads. Various objects are then rubbed against each other (wool against plastic, silk against glass, etc...) and each Styrofoam ball is charged by toughing. It is found that balls 1 and 2 repel each other and that balls 2 and 3 attract each other.

From this we can conclude (check all that apply).

2 and 3 carry charges of the same sign

we need more information to determine the sign of the net charge on each ball

1 and 3 carry charges of the opposite sign

all three objects carry charges of the same sign

1 and 2 carry charges of the same sign

1 and 2 carry charges of the opposite sign

2 and 3 carry charges of the opposite sign

1 and 3 carry charges of the same sign

Pith balls are small, lightweight objects that can pick up an electric charge. Suppose an experiment is performed and results show that Ball 1 attracts Ball 2. A third ball, Ball 3, is negative and repels Ball 2. What can be concluded about Ball 1 in terms of a charge sign and its value? Assign any charge to Ball 2 and Ball 3 as well as assign distances between all the charges. Assume that they lie on one the same...

You have three balls, each of which is placed at a particular location on the x-axis. Ball 1 has a mass of m, and it is located at x = 0. Ball 2 also has a mass of m, and it is located at x = −a. Ball 3 has a mass of 4m, and our goal is to determine where it is located. We do know that that magnitude of the net gravitational force experienced by ball 1, because...
