MCQ
A loop of light inextensible string passes over smooth small pulleys $A$ and $B$. Two masses $m$ and $M$ are attached to the points $O$ and $C$ respectively. Then the condition that $m$ and $M$ will cross each other. [Take $AB = 2l$ and $AC = AB = \eta l$] will be
- ✓$\frac{m}{M} > 2\sqrt {\frac{{\eta + 1}}{{\eta + 3}}} - 1$
- B$\frac{m}{M} > 2\sqrt {\frac{{\eta + 3}}{{\eta + 1}}} - 1$
- C$\frac{m}{M} > \sqrt {\frac{{\eta + 1}}{{\eta + 3}}} + 1$
- Dnone of these
