A) \[0{}^\circ \]
B) \[60{}^\circ \]
C) \[90{}^\circ \]
D) \[30{}^\circ \]
Correct Answer: B
Solution :
Work done \[W=F.s\cos \theta \] \[\text{cos}\,\text{=}\frac{1}{2}-\cos \,{{60}^{{}^\circ }}\] \[5=10\times 1\cos \theta \] \[\therefore \] \[\,\text{=60}{}^\circ \]You need to login to perform this action.
