A uniform rod of length l is suspended from a point P. and the rod is made to undergo small oxcillations. Match the following |
|
Answer» Correct Answer - `(A rarr t, B rarr t, C rarr s)` `T=2pisqrt((I)/(mgl))`. Here , l is distance of point P from centre of mass. When P is the centre , l=0. Therefore, `T=oo`, i.e., rod will not oscillate. When P is end point , `I=(ml^(2))/(3)` `therefore T=2pisqrt((l)/(3g))impliesT_("rod")=T_("pendulum")` or `2pisqrt((2l)/(3g))=2pisqrt((L)/(g))` or `L=(2l)/(3)` |
