Horizontal and vertical components of tension are shown in the figure.
Solution

From the figure,

T s in 3 0^{o} = 30

.....(i)

T cos 3 0^{o} = w

.....(ii)
By solving Equations (i) and (ii), we get

w = 303 N

and

T = 60 N

Q. As shown in figure, the tension in the horizontal cord is $30 N .$ The weight $w$ and tension in the string $O A$ in newton are

$303, 30$

$303, 60$

$603, 30$

None of the above
