Laws Of Motion Question 302
Question: For the given situation , the value of $ \theta $ to keep the system in equilibrium will be
Options:
A) $ 30{}^\circ $
B) $ 45{}^\circ $
C) $ 0{}^\circ $
D) $ 90{}^\circ $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] in eqbm $ T _{1}Cos\theta $
$ =T _{2}=60N. $ ..(i) $ T _{1}\sin \theta =60N $ ..(ii)
$ \therefore \tan \theta =1\Rightarrow \theta =45{}^\circ $
