A) \[30{}^\circ \]
B) \[45{}^\circ \]
C) \[0{}^\circ \]
D) \[90{}^\circ \]
Correct Answer: B
Solution :
[b] in eqbm \[{{T}_{1}}Cos\theta \] \[={{T}_{2}}=60N.\] ?..(i) \[{{T}_{1}}\sin \theta =60N\] ?..(ii) \[\therefore \tan \theta =1\Rightarrow \theta =45{}^\circ \]You need to login to perform this action.
