Question

A force is needed to keep a block of cork inside water. Give reasons

Answer 1

Yes because the density of block of cork is less than the density of water so buoyant force exerted by water in direction is high therefore we have to give force in downward direction.

Answer 2

Hlo mate :-

Answer :-


● The force that is required to keep a block floting on the water is equal to the buoyant force :-

● Which is equal to :-

■ density of water * mass of block * acceleration due to gravity
