Question
A block is partially immersed in a liquid and the vessel is accelerating upwards with an acceleration ″a″. The block is observed by two observers O1 and O2 , one at rest and the other accelerating with an acceleration ″a″ upward as shown in the figure. The total buoyant force on the block is :
Options
A.same for O1 and O2
B.greater for O1 than O2
C.greater for O2 than O1
D.data is not sufficient
Solution
Buoyant force = Fb = Vsub . ρl . g
where, Vsub , ρl and g all are same w.r.t. O1 and O2.
where, Vsub , ρl and g all are same w.r.t. O1 and O2.
