A conical vessel having base area `4xx10^3 m^2` and height 40 cm is filled with a liquid of density 0. 9 grarm/`cm^3`. What is the force acting on the base of the vessel due to the liquid column ?
[Use g`=10m//s^2`]

A

9.8 N

B

14.4 N

C

12.5 N

D

16 N

Text Solution

Verified by Experts

The correct Answer is:
B
Pressure due to liquid column`=rhogh`
and Force=Pressure`xx`Area
`:." "F=rhoghA`
`:'" "rho=9xx10^2kg//m^2,h=0.4m=4xx10^(-1)m`
`:." "F=9xx10^2xx10xx4xx10^(-1)xx4xx10^(-3)`
`=144xx10^(-1)=14.4N`
