A) \[30{}^\circ \]
B) \[60{}^\circ \]
C) \[45{}^\circ \]
D) \[75{}^\circ \]
Correct Answer: B
Solution :
[b] Net torque about \[P=0\] \[F\cos \theta (2R-R\,cos\theta )=F\sin \theta \,R\sin \theta \] \[2\cos \theta =1\] \[\Rightarrow \,\,\,\theta =60{}^\circ \]You need to login to perform this action.
