A glass of water sits on a scale. The scale reads 4.78 N. A steel bolt weighs 2.32 N. The density of steel is 7.86 g/cm3. We tie the bolt to a string and lower the bolt into the glass of water so that the bolt is fully submerged in the water but is not touching the bottom or side of the glass. (a) How much does the glass of water weigh (N) now? (b) What is the tensiorn (N) in the string?
