Q$5).10$ marks. Using a tubular$-$bowl centrifuge rotating at $3600$ r$.$p in$.,$ deter

terminal velocity of E$.$ coli in a saline solution $($density $p=1\mathrm{.}0\frac{g}{c}{m}^3)$ at a adial di

$cm$ from the axis. The cell size of $E.$ coli is approximately $0\mathrm{.}8mm$ wi ie and a

$2mm,$ with a volume of $10m{m}^3.$ Its density ${}_p$ is $1\mathrm{.}1\frac{g}{c}{m}^3.$ In calculation,

approximated as a sphere of $1\mathrm{.}25m$ diameter?
