Question

For the given situation as shown in the figure, the value of $\theta$ to keep the system in equilibrium will be

• A. $30^{\circ }$
• B. $45^{\circ }$
• C. $0^{\circ }$
• D. $90^{\circ }$

Answer 1

Answer: (B)

In eqbm,
$T_1\cos \theta =T_2=60N.\dots (1)$
$T_1\sin \theta =60N\dots (2)$
$\therefore \tan \theta =1\Rightarrow \theta =45^{\circ }$
