a.) What does the Volume Principle say?
Fluid tends to flow faster where the pressure is lower.

A cylindrical beaker of height 0.100m and negligible weight is filled to the brim with a fluid of density = 890 kg/m3.When the beaker is placed on a scale, its weight is measured to be1.00N.
A ball of density = 5000kg/m3 and volume =60.0cm3 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. Throughout the problem, assume the acceleration due to gravity is g = 9.81m/s2.

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 negative).
