Two different syringes having radii in the ratio 1: 5 are applied with same pressure. The forces acting on these syringes are in the ratio

Two syringes have piston in the ratio 1 : 5. If the pressure exerted in both syringes is same, find the ratio of the forces applied on the piston.

There are two identical small holes on the opposite side of a tank containing full of a liquid. The tank is open at the top. The difference in height between the two holes is ' $h$ '. As the liquid comes out of the two holes, the tank will experience a net horizontal force proportional to

A hydraulic lift is shown in the figure. The radii of the movable pistons \(P_1\) and \(P_2\) are \(2\,\text{m}\) and \(5\,\text{m}\) respectively. If a block of mass \(x\) is placed on \(P_2\), then the minimum mass that should be kept on \(P_1\) to lift the block on \(P_2\) is

In a hydraulic lift, compressed air exerts a force \(F\) on a small piston of radius \(3\;cm\). Due to this pressure, the second piston of radius \(5\;cm\) lifts a load of \(1875\;kg\). The value of \(F\) is
Take acceleration due to gravity \(g=10\;\text{m s}^{-2}\).

A hydraulic lift is shown in the figure. The radii of the movable pistons \(P_1\) and \(P_2\) are \(2\,\text{m}\) and \(8\,\text{m}\) respectively. If a body of mass \(2\,\text{kg}\) is placed on piston \(P_1\), then the force on piston \(P_2\) is \((\text{Ignore atmospheric pressure, acceleration due to gravity}=10\,\text{m s}^{-2})\)

To what height should a rectangular cylinder having square base of length 10 cm be filled, so that the total force on the bottom is equal to that on the sides ?
