✳QUESTION❇

Two cylindrical vessels fitted with pistons A and B of area of cross section 8cm² and 320cm2 respectively, are joined at their bottom by a tube and they are completely filled with water. When a mass of 4 kg is placed on piston A, find:
(i) the pressure on piston A.
(ii) the pressure on piston B, and
(iii) the thrust on piston B

PLEASE ANSWER!!☺​

Answer 1

GIVEN

Force applied on a narrow piston = 4kg

Area of cross section of A = 8cm²

Area of cross section of B = 320cm²

(i) Pressure on piston A =$\huge\frac{Thrust}{Area}$

=$\huge\frac{4}{8}$

=0.5kg/cm²

_______________________________

(ii) Pressure on Piston A = Pressure on Piston B

(as per Pascal's law)

Therefore,

Pressure on Piston B is 0.5kg/cm²

_______________________________

(iii) Thrust on Piston B is acting in the upward direction, which is given by

Pressure = Force / Area

=> 4kg × (320/8)

=> 4kg × 40

=> 160 kg
