Answer:
14.27 mm
Explanation:
Force = 80 Newton
Pressure exerted = 5 bar = 5×10⁵ Pa
Pressure exerted = Force/Area
Area = Force/Pressure
[tex]Area=\frac{80}{500000}\\\Rightarrow Area=0.00016\ m^2[/tex]
Area of the cylinder=πd²/4
[tex]\Rightarrow \frac{\pi}{4}d^2=0.00016\\\Rightarrow d^2=\frac{4\times 0.00016}{\pi}\\\Rightarrow d^2=0.0002037\\\Rightarrow d=0.01427\ m[/tex]
Hence diameter of cylinder 14.27 mm
