A massless, inextensible string of length 1 m has a breaking strength of 1 kg wt. A stone of mass 0.2 kg tied to one end of the string is made to move in a vertical circel. Can te stone decribe the vertical circle? `(g=10 ms^(-2))`

Explanation

`T_(max)=1 kg.wt=1xx10=10N`
Let tension at towest point be T
`T_(min)=6mg`
`T_(min)=6mg=6xx0.2xx10=12NgtT_(min)`
So, the stone cannot describe the vertical circel.
