A) \[\omega =0\]
B) \[\alpha =0\]
C) \[J=0\]
D) \[F=0\]
Correct Answer: B
Solution :
We know that, Torque (r) = moment of inertia (I) \[\times \] Agular acceleration (\[\alpha \]) As, \[\tau =0,\] so, either I or \[\alpha =0\] but \[I\ne 0\] \[\therefore \,\,\alpha =0.\]You need to login to perform this action.
