A) 3.6 N
B) 7.2 N
C) 9.0 N
D) 14.4 N
Correct Answer: B
Solution :
Pressure of liquid column \[=h\rho g\] \[p=0.4\times 900\times 10\,N/{{m}^{2}}\] 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 NYou need to login to perform this action.
