1. Two identical 15.0 kg balls, each 25.0 cm in diameter, are suspended by two 35.0 cm wires as shown in the figure. The entire apparatus is supported by a single 18.0 cm wire, and the surfaces of the balls are perfectly smooth.

Find the tension in the left 35.0 cm wire.

2. What is the tension in the right 35.0 cm wire?

3. What is the tension in the top 18.0 cm wire?

4. How hard does each ball push on the other one?
