Question

The given 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 (A) 10 N, 11 N (B) 10 N, 6 N (C) 10 N, 10 N (D) can't be calculated due to insufficient data

From the figure. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/3f6116cd5941f20557493dc6fcf38042-.png" /> T1 cos 30° =T2 cos 30° ∴ T1 =T2=T (Let) Again T1 sin 30°+T2 sin 30°=10 2 T sin 30°=10 2 T . (1/2) =10 ⇒ T=10 N ∴ Tension in section BC and BF are 10 N and 10 N

Q. The given 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 $BC$ and $BF$ are

10 N, 11 N

10 N, 6 N

10 N, 10 N

can't be calculated due to insufficient data

From the figure.

$T_{1} cos 3 0^{\circ} = T_{2} cos 3 0^{\circ}$
$∴ T_{1} = T_{2} = T$ (Let)
Again $T_{1} sin 3 0^{\circ} + T_{2} sin 3 0^{\circ} = 10$
$2 T sin 3 0^{\circ} = 10$
$2 T . \frac{1}{2} = 10$
$\Rightarrow T = 10 N$
$∴$ Tension in section $BC$ and $BF$ are $10 N$ and $10 N$
