One 24-g conducting pith ball has -6.4 µC of charge and touches an identical pith ball that is initially neutral. The diagram below (not to scale) shows the final configuration of the two pith balls as they hang from threads:

- Explain the value of the charge on each pith ball after they are separated.

- Construct a free-body diagram with symbols representing all the forces on the pith ball on the right.

- Calculate the value of all the forces on the pith ball in your free-body diagram.

- Determine the angle between the threads in the diagram above.
