Given: Two cylindrical vessels fitted with pistons A and B of area of cross section 8 cm² and 320 cm²
To find: the pressure on piston A ?
Solution:
- Now we have given area of cross section of piston A is 8 cm² and area of cross section of piston B is 320 cm² .
- So pressure acting on piston A will be in downwards direction.
Pressure = Thrust / area
Pressure = 4 kg / 8 cm^2
Pressure = 0.5 kg / cm^2
Answer:
So the pressure on piston A is 0.5 kg / cm^2.
