Answer to Question #70219 in Physics for hamid

Question

A wooden block is lying on the bottom of the tank sticking (with glue) to it. When water is poured into the tank, water does not enter below the block. Is there a buoyant force acting on the block? Explain." FLUID DYNAMICS

Answer 1

As known, the buoyant force arises when the pressure at the bottom of a wooden block placed in water is greater than at the top of the block.
Since wooden block is lying on the bottom of the tank and sticked to it the pressure at the bottom of a block is zero. So a buoyant force does not arise.
