A) \[r<\frac{\mu g}{{{\omega }^{2}}}\] only
B) \[r>\frac{\mu g}{{{\omega }^{2}}}\] only
C) \[r=\frac{\mu g}{{{\omega }^{2}}}\] only
D) \[r\le \frac{\mu g}{{{\omega }^{2}}}\] only
Correct Answer: D
Solution :
\[\mu mg=\frac{m{{v}^{2}}}{r}=m\omega v\] or \[\mu g=r{{\omega }^{2}}\] or \[r\le \frac{\mu g}{{{\omega }^{2}}}\]You need to login to perform this action.
