Q. The adjacent figure is the part of a horizontally stretched net. Section $AB$ is stretched with a force of 10 N. The tension in the section $BC$ and $BF$ are

A) 10 N, 11N
B) 10 N, 6 N
C) 10 N, 10 N
D) Can’t be calculated due to insufficient data
Explanation

(c) From the figure,
[image:5_image249.emf]
$T_{1}\cos{30{^\circ} = T_{2}\cos{30{^\circ}}}$
$\therefore\ \ T_{1} = T_{2} = T(Let)$
Again, $T_{1}\sin{30{^\circ}} + T_{2}\sin{30{^\circ} = 10}$
$2T\sin{30{^\circ} = 10}$
$2T\frac{1}{2} = 10\ \ \ \ \ \Longrightarrow T = 10\ N$
$\therefore\ $Tension in section BC and BF are 10 N and 10 N.
