APPARATUS
250 g spring scale 101-05-G4
overflow cylinder 202-16-A
600 ml beaker 101-01-C
mass 202-16-A
cup 202-16-A
video camera 202-09-D


DESCRIPTION
Hang the cup and ball from a spring scale and determine their weight.  Lower the ball into the filled cylinder and catch the overflow in the beaker.  The difference between the two scale readings is equal to the buoyant force.  Show that this is equal to the weight of the displaced water by pouring the overflow into the cup to re-establish the original reading.
 
NOTES
 
Make sure ball, cup, and string are initially dry.
