The adjacent figure is the part of a horizontally stretched net. Section A B is stretched with a force of 10 ~N . The tensions in the sections B C and B F are
Options
- A10 ~N , 11 ~N
- B10 ~N , 6 ~N
- C10 ~N , 10 ~N
- DCan't calculate due to insufficient data
Correct answer
C. 10 ~N , 10 ~N
Step-by-step solution
Let tension in section B C is T and in section B F is T₂ , then according to Lami's theorem, aligned T₁ 120^ = T₂ 120^ = T 120^ T₁=T₂=T=10 ~N aligned
