A cylindrical beaker of height 0.100m and negligible weight is filled to the brim with a fluid of density = 890kg/m^3 . When the beaker is placed on a scale, its weight is measured to be 1.00N.
A ball of density = 5000kg/m^3 and volume = 60.0cm^3 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 = 9.81 m/s^2.
What weight does the scale now show?© BrainMass Inc. brainmass.com March 21, 2019, 11:38 pm ad1c9bdddf
The solution determines the force applied to the ball by the rod.
