Questions
1. Compare the graphical and analytical (addition of components) methods for adding vectors. Which is more accurate? Give possible sources of error for both methods. Why is it useful to use both methods?
2. What are the possible sources of error in the experimental method? (Why is it necessary to allow the strings to slip loosely about the ring?)
3. If the weights of all the weight hangers were the same could their weight have been neglected? Explain.
4. What is the effect of the weight of the ring? What difference would it make if the ring were considerably more massive?
