A) \[\frac{\cos \theta }{{{\mu }_{0}}}\]
B) \[\frac{\sin \theta }{{{\mu }_{0}}}\]
C) \[\frac{tan\theta }{{{\mu }_{0}}}\]
D) \[\frac{2tan\theta }{{{\mu }_{0}}}\]
Correct Answer: C
Solution :
[c] Acceleration of mass at distance x \[a=g(\sin \,\,\theta -{{\mu }_{0}}x\cos \,\,\theta )\] Speed is maximum, when \[a=0\] \[g\left( sin\,\theta -{{\mu }_{0}}\,x\,cos\,\theta \right)=0\] \[x=\frac{\tan \,\theta }{{{\mu }_{0}}}\]You need to login to perform this action.
