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.
