<img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/b0aed7248646bf42cc54d8cf45dd21f7-.png" /> From Lamiâs theorem (B/ sin 135°) = (30/ sin 135°) B = 30 N

Q. In the figure shown, the tension in the horizontal cord is $30 N$ . Find the weight of the body $B$ .

40 N

30 N

20 N

10 N

From Lami’s theorem
$\frac{B}{s i n 13 5 ^{\circ}} = \frac{30}{s i n 13 5 ^{\circ}}$
$B = 30 N$

Q. In the figure shown, the tension in the horizontal cord is 30N . Find the weight of the body B .
