A) 3
B) 3.3
C) 0.27
D) 0.33
Correct Answer: C
Solution :
Retardation \[=\,\,\,g(sin\,\theta \,\,+\,\,cos\,\theta )\,\,=\,\,5(\sqrt{3}+\mu )\] Now \[v=u-at\] \[\therefore \,\,\,\,\,\,a\,\,=\,\,\frac{u}{t}\,\,\,as\,\,v\,\,=\,\,0\,\,\] \[\therefore \,\,\,\,\text{ }5\left( \sqrt{3}+\mu \right)=10\,\,\Rightarrow \,\,\mu \,\,=\,\,0.27\]You need to login to perform this action.
