A. Suppose you had an object that you suspected had a mass of one half of one of the washer+paperclip
units. (In the rest of this problem we’ll call that a “washerclip.”) Describe how you could use the balance you used in tutorial and a single washerclip to check this.

B. How could you use the balance to check that an object had a mass of one-fifth of one of your
washerclips?

C. Suppose you had a single washerclip and an object that you suspected had a mass of 5 washerclips.
How could you use your balance to check this?
