Question

The area of one end of a U-tube is 0.01 square and that of the other end is 1 metre square when a force was applied on the liquid at the first end the force experienced at the other end was 20000 N . What was the force applied on the liquid at the first end

Answer 1

$\LARGE\pink { \underline{\underline{\sf{꧁ᗩᑎՏᗯᗴᖇ꧂}}}}$

$\huge{A}\small{1} = 0.01m²$

$\huge{A}\small{2} = 1m²$

$\huge{F}\small{1 }= ?$

$\huge{F}\small{2 }= 20000N$

$\dfrac{ᗩ1}{ᗩ2}$=$\dfrac{ᗩ1}{ᗩ2}$

$ᖴ1=ᖴ2×\dfrac{ᗩ1}{ᗩ2}$

$20000×\dfrac{0.01}{1}$

$=200N$

Answer 2

A1=0.01m²

A2=1m²

F2=20000N

F1=???

$\frac{F1}{F2} = \frac{A1}{A2}$

$F1 = F2 \times \frac{A1}{A2}$

$= 20000 \times \frac{0.001}{1}$

$200N$
