A uniform rod of length 1 and mass m is suspended by two vertical inextensible string as shown in the fig. The tension in the left string when right string snaps, is

Explanation

`mg-T=ma " "…(1)`
`alpha=(tau)/(I)=(mg(l)/(2))/((ml^(2))/(3))=(3g)/(2I) " "…(2)`
`a=(l)/(2) alpha ….(3)`
solving equation (1), (2) and (3)
we get `T=(mg)/(4)`
