Question

A body of weight 2kg is suspended as shown in the figure. The tension $T _ { 1 }$ in the horizontal string (in kg wt) is

• A. $2 / \sqrt { 3 }$
• B. $\sqrt { 3 } / 2$
• C. $2 \sqrt { 3 }$
• D. $2$

Answer 1

Answer: (C)

$2 \sqrt { 3 }$

Answer 2

$T \sin 30 = 2 \mathrm {~kg} w t$

⇒ $T = 4 \mathrm {~kg} w t$

$T _ { 1 } = T \cos 30$ °

$= 4 \cos 30$ °

$= 2 \sqrt { 3 }$
