The adjacent figure is the part of a horizontally stretched net. section AB is stretched with a force of 10 N . The tensions in the sections BC and BF are

Answer

10

Explanation

By drawing the free body diagram of point B
Let the tension in the section BC and BF are `T_(1)` and `T_(2)` respectively.
From Lami’s theorem
`(T_(1))/(sin 120^(@)) = (T)/(sin 120^(@)) implies T_(1) = T = 10 N.`
