A large mass `M` and a small mass `m` hang at the two ends of string passing through a smooth tube. The mass `m` moves around in a circular path in a horizontal plane. The length of the string from the mass `m` to the top of the tube of the tube is `l` and `theta` is the angle this length makes with the vertical. What should be the frequency of rotation of the mass m so that M remains stationary ?

A

`1/2pisqrt(Mg)/(ml)`

B

`1/2pisqrt((ml)/(Mg))`

C

`1/2pi sqrt((mg)/(Ml))`

D

`1/2pisqrt((mM)/(gl))`
