Vectors Question 120
Question: As shown in figure the tension in the horizontal cord is 30 N. The weight W and tension in the string OA in Newton are
[DPMT 1992]
Options:
A) 30 $ \sqrt{3}, $ 30
B) 30 $ \sqrt{3}, $ 60
C) 60 $ \sqrt{3}, $ 30
D) None of these
Correct Answer: B From the figure $ T,\sin 30^{o}=30 $ ?(i) $ T\cos 30^{o}=W $ ?(ii) By solving equation (i) and (ii) we get $ W=30\sqrt{3}N $ and $ T=60N $
