Question

In the following figure, the tension in the horizontal cord is 30 N.What is the weight of the body B?

• A. 40 N
• B. 30 N
• C. 20 N
• D. 10 N

Answer 1

The correct option is B 30 N

Let weight is $W$ and tension in cord $2$ $T.$

$\frac{T}{\sqrt{2}}=30$

$\frac{T}{\sqrt{2}}=W$

$\Rightarrow W=30N$
