A ball of density (with ) and volume is then submerged in the fluid, so that some of the fluid spills over the side of the beaker. The ball is held in place by a stiff rod of negligible volume and weight.
A) What is the weight of the ball? (in N)
B) What is the reading
of the scale when the ball is held in this submerged position? Assume
that none of the water that spills over stays on the scale. ?
C) What is the force
applied to the ball by the rod? Take upward forces to be positive
(e.g., if the force on the ball is downward, your answer should be
The rod is now õtnx.Hmtached to the bottom of the beaker.
beaker is again filled with fluid, the ball is submerged and attached
to the rod, and the beaker with fluid and submerged ball is placed on
the scale. (Intro 2 figure)
D) What weight does the scale now show?
I do not know how to do D.
