If initial tension is zero. then 2△Tsin △θ=mg △T=((mg)/(2sin △θ)) very naturally if △θ<30° ⇒ △T=((mg)/(2sin △θ)) >mg .
$$\mathrm{If}\:\mathrm{initial}\:\mathrm{tension}\:\mathrm{is}\:\mathrm{zero}. \\ $$$$\mathrm{then}\:\:\:\:\mathrm{2}\bigtriangleup\mathrm{Tsin}\:\bigtriangleup\theta=\mathrm{mg} \\ $$$$\bigtriangleup\mathrm{T}=\frac{\mathrm{mg}}{\mathrm{2sin}\:\bigtriangleup\theta} \\ $$$$\:\mathrm{very}\:\mathrm{naturally}\:\mathrm{if}\:\bigtriangleup\theta<\mathrm{30}° \\ $$$$\Rightarrow\:\:\bigtriangleup\mathrm{T}=\frac{\mathrm{mg}}{\mathrm{2sin}\:\bigtriangleup\theta}\:>\mathrm{mg}\:. \\ $$$$ \\ $$

double tap to type text.after you have typed it you can move it change size color font group them rotate them and copy them or entirely delete it.
