A beaker, filled to the very topwith water, weighs 15 N. A 300 g
weight is carefully dropped intothe beaker. The water that
overflows is wiped away and the beakerreweighed. It weighs 16.9 N.
What is the densityof the weight? [Use g=9.8m/s2.]
Hint: The netforce on the bottom of the beaker after the weight is
lowered tothe bottom is (the weight of the reduced volume of water)
+ (300 gweight).
Thebeaker is refilled to the top with
