Current Question (ID: 10517)

Question:

$\text{The area of cross-section of the wider tube shown in the figure is 800 cm}^2\text{. If a mass of 12 kg is placed on the massless piston, then the difference in heights h of the levels of water in the two tubes will be:}$

Options:

1. $\text{10 cm}$
2. $\text{6 cm}$
3. $\text{15 cm}$
4. $\text{2 cm}$

Solution:

$\text{Pressure should be same on both sides.}$ $P = \frac{12g}{800} \times 10^{-4} = h \times 10^3 \times g$ $h = \frac{12}{80} \text{ m} = 15 \text{ cm}$
