A) 1/4
B) 1/2
C) 2/3
D) 1/3
Correct Answer: A
Solution :
\[{{F}_{1}}=\frac{\left( {{P}_{1}}+{{P}_{2}} \right)}{2}A\] \[{{F}_{2}}=\frac{\left( {{P}_{2}}+{{P}_{3}} \right)}{2}A\] \[\therefore \,\,\,\,\,\,\,\,\frac{{{F}_{1}}}{{{F}_{2}}}=\frac{5\rho g}{20\rho g}=\frac{5}{20}=\frac{1}{4}\]You need to login to perform this action.
