A wheel of moment of inertia 10 kg

{m^2}

is rotating at 10 rotations per minute. The work done in increasing its speed to 5 times its initial value, will be

\left( {{P^2}\,\, \approx \,\,10} \right)

View answer and explanation

Correct option: B

133.3 Joule

Option B (133.3 Joule) is correct because it is the work done calculated from the change in rotational kinetic energy when the angular speed increases fivefold.
