Rotational MotionHard

Question

If a body completes one revolution in π sec then the moment of inertia would be : -

Options

A.Equal to rotational kinetic energy
B.Double of rotational kinetic energy
C.Half of rotational kinetic energy
D.Four times of the rotational kinetic energy

Solution

= 2 rad /sec.
K.E = Iω2 ⇒ I = ⇒ I =
