A block of weight 100 N is suspended (as shown) with the help of there strings. Find the tensions in the three strings).

Explanation

Free body diagram of block

`rArr" "T_(0)=100N`
Free body diagram for point O
From figure
`T_(0)=T_(2)cos 60^(@)`
`T_(2)=(100)/(cos60^(@))=(100)/(1//2)`

`T_(2)=200N`
`T_(1)=T_(2)sin 60^(@)=200xx(sqrt3)/(2)rArr T_(1)=100sqrt3" Newton"`
