Question 10

A test-dummy of mass 3m is secured inside a centrifuge cabin that rotates in a horizontal circular path of radius 2R2R2R. The centrifuge completes one full revolution in a time period TTT.

What is the kinetic energy of the test-dummy?

A
24π2mR2T2 \frac{24\pi^2 m R^2}{T^2} T224π2mR2​
B
12π2mR2T2 \frac{12\pi^2 m R^2}{T^2} T212π2mR2​
C
6π2mR2T2 \frac{6\pi^2 m R^2}{T^2} T26π2mR2​
D
48π2mR2T2 \frac{48\pi^2 m R^2}{T^2} T248π2mR2​
