The area of cross-section of the wider tube shown in fig., is `800cm^(2)` . If a mass of 12 kg is placed on the massless piston, what is the difference in the level of water in two tubes.

A

10 cm

B

6 cm

C

15 cm

D

2 cm

Text Solution

Verified by Experts

The correct Answer is:
C
`hrhog=(12g)/(800xx10^(-4))" "implies hxx1000=(12xx10^(4))/(800)`
`h=(120)/(800)m" "impliesh=15cm`

A long cylindrical tank of cross-sectional area 0.5m^(2) is filled with water. It has a small hole at a height 50cm from the bottom. A movable piston of cross-sectional area almost equal to 0.5m^(2) is fitted on the top of the tank such that it can slide in the tank freely.
