Two liquids of densities p(1) and p(2) ...

Two liquids of densities `p_(1) and p_(2) (p2_= 6 p1 ) ` are filled up behind a square wall of side 8 m as shown in figure. The liquids have height as shown. 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)

A

23/80

B

25/84

C

`1//3`

D

`1//2`

Text Solution

Verified by Experts

The correct Answer is:
B
`F_(1) = (5pg)/(2) xx 5A`
`F_(2) = (5pg + (6pg xx 3)/(2))3A`
(F_(1))/(F_(2)) = (25)/(84)`
