Question

A mass m is hung with a light inextensible string as shown in figure. The value of tension T₁ is​

Answer 1

Answer:

Explanation-[7

Answer 2

as it is given that

T1 is  the tension of horizontal part of string.

we use from FBD,$\mathrm{T}_{2} \sin 30=\mathrm{Mg} \Rightarrow \mathrm{T}_{2}=2 \mathrm{Mg}$

and

$\mathrm{T}_{1}=\mathrm{T}_{2} \cos 30=2 \mathrm{Mg} \times \frac{\sqrt{3}}{2}=\sqrt{3} \mathrm{Mg}$
