A constant torque of 100 ~N ~m turns a wheel of moment of inertia 300 ~kg ~m ^2 about an axis passing through its centre. Starting from rest, its angular velocity after 3 ~s is

Options

  1. A10 rad / s
  2. B15 rad / s
  3. C1 rad / s
  4. D5 rad / s

Correct answer

C. 1 rad / s

Step-by-step solution

About fixed axis Torque =I aligned & = 100 300 & = 1 3 rad / s ^2 aligned aligned & _i=0 & _f= _i+ t & at t=3 ~s & _f= 1 3 3=1 rad / s aligned
