ANSWER:
Step 1 of 3
Part (a)
Our aim is to find the force exerted on the flat end of the flat surface of the cylinder.
The diameter of the cylinder \(\mathrm{d}=60 \mathrm{~cm}\)
The radius of the cylinder \(\mathrm{r}=0.30 \mathrm{~m}\)
The acceleration due to gravity \(\mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^{2}\)
The atmospheric pressure \(\mathrm{p}_{0}=101.3 \mathrm{kPa}=101.3 \times 10^{3} \mathrm{~Pa}\)
