A) \[{{60}^{o}}\]
B) \[{{90}^{o}}\]
C) \[{{30}^{o}}\]
D) \[{{45}^{o}}\]
Correct Answer: C
Solution :
Bil \[\sin \theta =F\Rightarrow 2\times 5\times 1.5\sin \theta =7.5\] \[\Rightarrow \] \[\sin \theta =\frac{7.5}{2\times 5\times 1.5}=\frac{1}{2}=\sin {{30}^{o}}\] \[\therefore \] \[\theta ={{30}^{o}}\]You need to login to perform this action.
