A piston of cross-section area 100 cm 2 ...

A piston of cross-section area 100 cm 2 is used in a hydraulic press to exert a force of `10^(7)` dynes on the water. The cross-sectional area of the other piston which supports an object having a mass `2000 kg`. Is

A

`9.8xx10^2 cm^2`

B

`9.8xx10^3 cm^2`

C

`1.96xx10^3 cm^2`

D

`1.96xx10^4 cm^2`

Text Solution

Verified by Experts

The correct Answer is:
D
As , `F_1/A_1=F_2/A_2 " "` (pascal's law)
`therefore A_2=F_2/F_1.A_1=((2000xx9.8)/(10^2))(100)=1.96xx10^4cm^2`

The mechanical advantage of a hydraulic press is 5. A car of mass 1500 kg is lifted by when placed on a piston of a hydraulic press of area of cross section 5 m^(2) . Find the area of cross section of pistion of piston where the effort is applied.

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. A load of 20 kg is applied on the top of the water by piston, as shown in the figure. Calculate the speed of the water jet with which it hits the surface when piston is 1m above the bottom. (Ignore the mass of the piston)

A rigid cylindrical container having a cross sectional area of 0.2 m^(2) is filled with water up to a height of 5.0 m . There is a piston of negligible mass over the water. Piston can slide inside the container without friction. When a weight of 2000 kg is placed over the piston, it moves down by 0.25 mm compressing the water. rho= Density of water = 10^(3) kg//m^(2), P_(atm)= Atmospheric pressure =10^(5) N//m^(2) and g=10 m//s^(2) . With this information calculate the speed of sound in water.
