Question

A cubical block of wood 10cm on a side,floats at the interface of oil and water find gauge pressure at top and bottom

Answer 1

Answer :

680

Explanation:

As the box is in equilibrium, thus the weight of the box is balanced by the total buoyancy force.

∴ Mg=ρ

w

(2×10×10)g+ρ

o

(8×10×10)g

OR M=1(200)+0.6(800)g

⟹ M=680g
