Question 26

A capsule of mass $M$ undergoes spin-trials in a centrifuge, moving in a circle of diameter $D$ . The centrifuge completes $n$ full revolutions per second. What is the kinetic energy of the capsule?

$12π2Mn2D2\frac{1}{2} \pi^2 M n^2 D^2$

$\pi^2 M n^2 D^2$

$18π2Mn2D2\frac{1}{8} \pi^2 M n^2 D^2$

$π2Mn2D2\pi^2 M n^2 D^2$
