Question 162: Properties of Matter

Question

Two liquids of densities $${\rho _1}$$ an $${\rho _2}$$ ($${\rho _2}$$ = 2$${\rho _1}$$) are
filled up behind a square wall of side 10 m as
shown in figure. Each liquid has a height of
5 m. The ratio of the forces due to these liquids
exerted on upper part MN to that at the lower part
NO is (Assume that the liquids are not mixing)

Accepted Answer

Force F
1
on MN = $${{ho gh} \over 2} 	imes A$$
Force F
2
on NO = $$\left( {ho gh + {{2ho gh} \over 2}} ight) 	imes A$$
$${{{F_1}} \over {{F_2}}} = {1 \over 4}$$
