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

A

`30sqrt(3),30`

B

`30sqrt(3),60`

C

`60sqrt(3),30`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B

From the figure `T sin 30^(@) = 30`….(i)
`T cos 30^(@)= W` ….(ii)
By solving equations (i) and (ii), we get
`W= 30sqrt(3)N` and `T= 60 N`
