A) 3.6N
B) 7.2N
C) 9.0N
D) 14.4N
Correct Answer: B
Solution :
Pressure of liquid column \[=\text{ }h\rho g\] \[P=0.4\times 900\times 10\,N/{{m}^{2}}\] Force on the base \[=P\times area\] \[=P\times 2\times {{10}^{-3}}\,{{m}^{2}}\] \[=0.4\times 900\times 10\times 2\times {{10}^{-3}}N\] \[=7.2\,N\]You need to login to perform this action.
