A uniformly tapering vessel is filled with a liquid of density 900 kg/m3. The force that acts on the base of the vessel due to the liquid is (g=10ms−2)(g = 10ms^{- 2})

A

3.6 N

B

7.2 N

C

9.0 N

D

14.4 N

Answer

7.2 N

Explanation

Solution

Force acting on the base F=P×A=hdgAF = P \times A = hdgA

=0.4×900×10×2×10−3=7.2N\mathbf{= 0.4}\mathbf{\times}\mathbf{900}\mathbf{\times}\mathbf{10}\mathbf{\times}\mathbf{2}\mathbf{\times}\mathbf{1}\mathbf{0}^{\mathbf{-}\mathbf{3}}\mathbf{= 7.2N}
