In Q. 133, if the strip is deflected slightly from its equilibrium position in the plane of the figure, the time period of the resulting oscillation is given by :

Answer»

`(sqrtl)/([g^(2)+((P)/(mc))^(2)]^(1/4))`
`sqrt((l)/(g^(2)+(P)/(mc)))`
`sqrt((g^(2)+(P)/(mc))/(l))`
none of these

Solution :In EQUILIBRIUM the TENSION is
`T=[(mg)^(2)+((P)/(C))^(2)]^((1)/(2))`
or `(T)/(m)=[g^(2)+((P)/(mc))^(2)]^((1)/(2))`
This playes the ROLE of EFFECTIVE g.
This period of small osicllation is
`t=2pi sqrt(((l)/(T))/(m))=2pi (sqrt(l))/([g^(2)+((P)/(mc))^(2)]^((1)/(4)))`
