A) \[\sqrt{\frac{g}{2R}}\]
B) \[\sqrt{\frac{g}{R}}\]
C) \[\sqrt{\frac{R}{g}}\]
D) \[\sqrt{\frac{2g}{R}}\]
Correct Answer: A
Solution :
\[v=\sqrt{2gR}\] \[\frac{M}{2}\times \sqrt{2gR}\times R=\frac{1}{2}\times M\times {{R}^{2}}\omega \] \[+=\frac{M}{2}+\frac{M}{2}\times R\times (R\omega )\] \[\Rightarrow \omega =\sqrt{\frac{g}{2R}}\]You need to login to perform this action.
