A) \[\omega =0\]
B) \[\alpha =0\]
C) \[J=0\]
D) \[F=0\]
Correct Answer: B
Solution :
\[t=I\,\alpha \] (where \[\tau =\] torque) \[I=\,\]moment of inertia \[\alpha =\,\]angular acceleration if \[\tau =0\] \[I\,\,\alpha =\,0\] But \[I\,\,\ne \,0\] \[\therefore \alpha \,\,=\,0\]You need to login to perform this action.
