A fly wheel of M.I

6 \times {10^{ - 2}}\,kg\,{m^2}

is rotating with an angular velocity of

\,20\,rad\,{s^{ - 1}}

. The torque required to bring it to rest in 4 s is

View answer and explanation

Correct option: D

0.3 Nm

Option D (0.3 Nm) is correct because it is the torque required to produce the necessary angular deceleration to bring the flywheel to rest in 4 seconds.
